What is smart study is that you should know what do I have to study and in what way do I have to study, now what do I have to study, son, after analysing the previous year questions of last 10 years, which topics questions are asked, son, if you analyse the last 10 years, then you will observe that questions are asked from some selected topics only, now approximately your 80 marks are made from 20 topics, 

Introduction :  

we are going to talk about those 20 topics from which mostly you will be asked questions, what kind of questions will come, what kind of questions are made from which topic, what are the important questions of NCERT, look son, I am not saying that read only these topics, you should read all of them, it's on you, but I will tell you that at the start of any chapter Before doing this, reading these topics will be of great help to you and if you are going to give any exam, but whatever pre-board half year exams you will get, son, you should prepare according to it, your marks will not be deducted at all, I have to ask two things, first of all, tell me how many chapters you have already mastered. what is your goal, how many percent marks do you want to get in the boards, so that you do not have even a single doubt, so the first chapter, son, we have a solution which is of seven marks, whenever you will read the solution, first of all you will read the concentration terms, mole fraction, molarity, molality and what is the relation between molarity and molality, what difference does temperature make, this is very important, let's move ahead, we have to study Henry's law, we have to read Routh's law and Routh's law From that itself, ideal non ideal son, see, there are not very big questions in the paper, I mean there is a question of five marks, but it is in parts, so you have to focus on the concept, right?
 

What is smart study is that you should know what do I have to study and in what way do I have to study, now what do I have to study, son, after analysing the previous year questions of last 10 years, which topics questions are asked, son, if you analyse the last 10 years, then you will observe that questions are asked from some selected topics only, now approximately your 80 marks are made from 20 topics, 
has released the sample paper for 2025 right now.

Syllabus : 

I have uploaded its analysis and solution, you guys can check it, I will provide the link in the description. Questions related to Henry's constant are asked that it is directly proportional to temperature and inversely proportional. There are two types of non-ideal solubility, positive deviation, negative deviation. Tell me why there is positive deviation because the force of attraction is weaker in it. Why does negative deviation occur because the force of attraction is strong in it. After that their azeotropic properties are
most important and there are four colligative properties, relative lowering, depression in freezing point, elevation in boiling point, osmotic pressure, most numerical questions are asked about depression in freezing point, and if I tell you which is considered the best tive property, osmotic pressure and the vent of factor is integrated in it, the vent of factor, you must know that the value of naclo3 is one, the value of alcl3 is four and glucose, urea, sucrose are non-electrolytes.

NCERT Syllabus : 

 If these do not dissociate in ice then their value is one. You people are asked degree of dissociation degree of association degree of dissociation i -1 ba n -1 degree of association i -1 1 / n - 1 and these are important questions of our NCERT according to the previous book, if you want to do it according to the new book, then the name and number of that chapter like solution is the first chapter, make it one, it is fine, you should try the first question of NCERT, let's move ahead, our chapter of highest marks is electro chemistry which is of nine marks, so first of all you will see the electrochemical cell, you will see its diagram and in it you will read that if the external potential is equal to 1.10 volts is less than 1.10 volts is more than 1.10 volts after that, briefly a question is formed from the equation, right, and the next form of the equation is ea delta gi kisi, you should look at this carefully Related numericals are formed, after this comes coalesce low and a graph is formed from here, isn't it the strong electrolyte one, the weak electrolyte one, which one is it, this is the weak one and this is the strong one, whose graph is formed of the root of delta a versus concentration, okay, the limiting molar conductivity of any electrolyte depends on the sum of individual contributions of cutay and anayat, we get fuel low, after this comes electrolytic conductance, our coalesce low is also formed in electrolytic conductance and what is conductance, son, it is directly proportional to the concentration, it is inversely proportional to the dilution, the question is formed from here and the molar conductance, which is the molar conductivity, is directly proportional to the dilution, it is inversely proportional to the molar concentration, after this, the cells which are primary, secondary, fuel cell, coreg secondary cell, reaction has been asked many times and you We should know the use of each of these cells, what is their use, well the question is made from the use and these are our important NCERT questions, after this we move ahead, next we have the chapter.

In chemical kinetics, you would have been given the rate law or the expression and you would be asked to tell the order of the reaction. Order is sum of power. Apart from this, you would be told that I have increased the same concentration two times or three times. So tell me what is the relation between new rate and old rate. Apart from this, the unit of rate constant is asked for different orders, right? Or you would have been given the unit and you would be asked the order. Well, what is the formula of rate constant unit for different orders? Mole per litre power 1 - n per second order and the difference factors affecting rate of molecule T. This is asked in the integrated rate equation which we have first order, from here many numericals are formed and the graph is zero order, first order and we have the RNS equation, you will see its graph very well, son, there is a 99% chance that the graph is formed from chemical kinetics. Come here, many first order numericals are formed, right? Tell me, if a reaction If it is taking 30 minutes to reach 50, then tell me how much time will it take to reach 75; a reaction takes 20 minutes to reach 20, then tell me how much time will it take to reach 80, such questions are formed, okay son, these are going to be important NCERT questions, before moving ahead, let me tell you son, I have provided you very good lecture notes, every child should download this app, from time to time I also keep taking free lectures and you will find many more courses, you should definitely download it and on this channel, one short 30 minutes, 15 minutes and now 60 minutes, apart from this, previous year questions, important NCERT questions of previous year I have uploaded MCQs etc. These will help you a lot, you can check them out as well. You will find the link in the description. Let's move ahead. Let's move on to chemistry. I recommend everyone to go to the passing range first. So first you guys have to do physical chemistry properly. When your physical chemistry becomes good, then you can move on to chemistry. There is an easy chapter on d and f block elements. Properties come in it and on what do the properties depend? On electronic conformation, zinc, cadmium, mercury are slightly different from d block elements. Maximum elements of d block have transitions but these are not transitions because they have a fully filled d orbital. After this, the properties are oxidation state. Variable oxidation states show. Why do they show because their bonds are very strong. They are very hard because they have unpaired electrons. They form coloured ices. Because of unpaired electrons, alloys are formed due to dd transition. Interstitial compounds make very good catalysts and what is the reason for this.

Topics For CBSE Exams : 

Ability to adopt multiple oxidation state, after this the preparation of kmno4 k2c 27 takes place and their properties are i2 is formed from ion active, sulphide forms sulphur, phosphite positive forms fe3 positive and let me tell you at one place if you take kmno4 in alkaline medium then aa negative forms iodate. This has been asked many times, if you go to f block, then a lot of lanthanide contractions are asked due to its consequences, the difference between 4f and 5f is asked and son, we have these important NCERT questions, you should do them well and move ahead, next coordination compound, coordination compound is a chapter to be read serially, first of all its introduction, what are coordination compounds, what are ligands, right, what is oxidation state, what is coordination number, read it very well, then you guys will be able to do nomenclature from ligands Related questions become which are bidentate ligands which are polydentate which are am dentate apart from this which are chil ing ligands which are chelate ones which are complexation stable this question is asked many times and why are they extra stable because they form cyclic compounds they have extra stability after this isomerism there are two types of isomerism structural stereo structural ionization coordination linkage hydrate ionization which will give different ions what will be the shortcut of coordination if two spheres are formed somewhere apart from this linkage if ever adent ligand comes then we have linkage isomerism hydrate water molecule you will see more or less stereo isomers if we talk about cistron it is a simple shortcut of optical coordination number should be six and there should be at least one bidentate ligand it is clear after this come to theory werner theory what does werner theory tell us about primary valency about secondary valency what is primary valency Oxidation number is called and what is secondary valency, coordination number is the most important son, valence bond theory is because it tells us the hybridized character and you guys can also answer even the color, isn't it hybridized sp3, tetrahedral d2 sp3 or sp3 d2, then octahedral d2 sp3, so when are these inner orbital complexations formed, generally when there are strong ligands, strong ligands cn3 and there is also an ox oxalato, which is with cobalt, right, the most famous question of CFT crystal field theory is this, brother, the delta t, the splitting energy of tetrahedron is 4/9 times of delta o and what question is asked, the splitting energy of strong field ligands is more than the pairing, the pairing energy of weak field ligands, sorry, in these cases the pairing energy is more and this, son, we have this important question of NCERT This is a good question. I would like to share some other important information with you.

After studying from our batch, if you feel that sir, I have taken offline tuitions but I am not able to understand, or even I am studying online from XYZ place, I am not getting that feeling, can I score well, son, if you are ready to work hard, if you are ready to study for two hours daily, then yes, there is a batch for you, Karna Pro batch, which is our best batch, in this batch the entire syllabus will be covered well and our future coming batches are PYQ batch, sample paper batch, fast revision batch, 2.2 batch, you will get access to all of these, this is the best batch, you will get the link of it in the description, if you want, you can take it [music] youtube1 sn2 sn1 follows a two-step mechanism, it follows a one-step mechanism, what matters here, the stability of carbocation matters, in sn2 there is less steric binding, so what will be the level of reactivity in sn2, primary is the most reactive then secondary is the most reactive, here let us talk about benzyle the most, then allyl Mostly they do not come, the most reactive is tertiary, then secondary and the least is primary, what happens here, son, racemization of configuration and what is seen here, you are going to see inversion of configuration, let's talk about some examples, like if the reaction of A is done, then KCA ACA will be formed, what are these, adents are nucleophiles, if I do the reaction of KCA, then it will link from the side of c, if I do the reaction of A, then it will link from the side of n, I have told a shortcut for this, no, if silver comes anytime, then linking takes place from the side of nitrogen, son, it is clear, let's move ahead, next we get a name reaction, like woods fitting woods phytic finkel strain swats one and I will talk about dose process, there is one marconic flower, anti marconic farul what is the shortcut of marconic farul whenever there is addition, Nathu Lal Halwai where will the negative portion go to the lower hydrogen, rule of anti marconic of nat hara halwai negative will go to higher hydrogen, if you ever Also see this, what is alcoholic, then what reaction will happen there, brother, elimination reaction is going to happen, these will be our important NCERT questions, after this we will get the chapter, alcohol, phenol ether, read as many chapters of organic, try to read serially, alcohol, phenol ether comes, you will also find many topics of this in aldehyde, ketose, come here, there is a very important reaction here, what is kerbs rime time Williamson kerbs, like you guys have done the benzene reaction with which, with na2, with hclo3 and h, then this will become celis aldehyde and what is the shortcut of Williamson synthesis, Rona hello, in the memory of alkane, na0 will be formed with us, come, when we come to the topics of acidic strength, so remember that electron withdrawing group increases the acidic strength, electron donating group increases the basic strength, the acidic strength is decreased, son, it is clear, after this see the mechanism, son, we have to study four mechanisms of class 12th boards For this, one is that of nucleophilic substitution and the three mechanisms which are there in this chapter are first hydration of alkene dehydration of alcohol to alkene dehydration of alcohol to ether read these carefully you can become any one of these is fine after this there are two-three tests like Lucas test what is the use of Lucas test to distinguish primary secondary terts we will use Lucas reagent in this what is Lucas reagent a mixture of hclo2 reaction will be slowest in primary alcohol it will have to be heated in secondary after 5 minutes you will see turbidity you will get to see immediate reaction in terts after this we have very important reaction of Grignard reagent if you treat Grignard reagent on formal aldehyde primary alcohol is formed if you treat on aldehyde secondary alcohol is formed and if you treat on ketone then we have tert alcohol is formed this will also help you in conversion okay If you do oxidation of primary alcohol, then what is formed? Oxidation of primary alcohol forms aldehyde and oxidation of secondary alcohol forms ketone. 

Let's move ahead. Next, let's talk about the biggest chapter of organic chemistry, aldehyde, ketone and carbosynth. What are the name reactions like Rosen-Mann reduction, Stephens reduction, Itard reaction, Gutterman, Clemens reduction, Wolff Kissen reduction, Aldol condensation, Cani, Jarrow reaction, Cross aldo. Apart from this, the HV Judd reaction is a very important reaction. You should know which reaction words where. Like Rosen-Mann reduction on benzoyl chloride, Stephens reduction on cyanide, Itard on toluene. After Gutterman, Koch, benzene, Sasi, Clemens reduction and Wolff Kissen, what do they do? They reduce aldehyde and ketone and convert it into hydrocarbon. Where is aldol condensation applicable? On those organic groups, on those organic compounds that have alpha hydrogen. Yes, it is the HV reaction in which carbocysteine ​​is formed, it is clear, two-three tests come, Tollens test failing, there is a high chance of solution iodoform test failing.

Let's see for which the Tollens test is applicable, Fehling's test for every aldehyde, iodo form test for aliphatic aldehyde, ethanol, methyl ketone and some such alcohols, ch3ch, now you must be finding my words strange, this is very simple, go to the start of any chapter, son, see this first, yes friend, sir has told these important topics, you should do them well, okay, I have already told you about the acidic strength, the carbon synthetic drawing group increases the acidic strength and the electron donating group decreases, okay, if you have an alkyne benzene, react it with kmno4 k, then it will always convert into your carboxy acid, nucleophilic addition reaction is shown by which carbon compounds and the more the bulk groups there are, like here there is one alkyne group, here there are two alkyl groups, then the reactivity towards nucleophilic addition reaction decreases, this is the most reactive, this is the least reactive This is an important NCERT question. After this, we have a small chapter, which is completed. There are reactions named after the selected dis, such as Gabriel Thalima Ide synthesis and carbene reaction Hofmann bromide degradation. This is very important. Many questions are asked from Hofmann bromide degradation. Okay, questions are asked from basic strength, so what will be the basic strength in gaseous state? What will be the basic strength in tertiary secondary primary aqueous solution? Basic strength in aqueous solution depends on three factors, inductive effect, standing effect, solvation effect, if there is methyl group, then what will be the rate of basic strength? It is 213, and if there is ethyl group, if there is ethyl a mine somewhere, then 2 3 one basic strength is directly proportional to each other, it means that the dissociation constant of bases is inversely proportional to each other. Look at the diazote egestion reaction of the cab very carefully, it is the diazote egestion reaction, which will form dizone salt and then many other reactions are formed from it, sand Meyer Gutterman coupling, apart from this there is Bal Sackman, and apart from this there are many many convergences as well, okay, if you want to control the activity of aniline, then such egestion is done, come forward, next and last bio molecule, bio molecule means a chapter which can be adjusted with a push, this is of bio but it is said that there is chemistry in me as well, keep me in chemistry for some time as well, so this is how we study it, the most important thing for us is carbohydrates, in carbohydrates, glucose is found in mono saccharide, read glucose in great detail, brother, its structure, its reactions and it has some exceptions, it does not show some special reactions, in di saccharide we have sucrose which is formed by combining glucose and fructose, maltose is formed from glucose and glucose, and lactose is formed by combining glucose and If we talk about poly saccharide from galactose, then the starch is amize and amize patin has two parts, in this amize is at 20 and amize pectin is at 80. Coming to the proteins, the most important difference is formed, the most important is the difference between fibrocystic acid, the most important is the difference between DNA and RNA, isn't it? What is common in these? AGC is common in both, in this, T is a new thing and in this, Y is a new thing, thymanum is extra, in this, uracil is extra, isn't it? What is called a nucleotide, which has a base, sugar, phosphate group, what is called a nucleoside, which has a base and sugar, and in the end what do we get, son, vitamins, deficiency disease of vitamins, so this is, son, the important topic of our entire chemistry, I have told you how questions are framing and you also how to answer them.

I have also told you this, so once carefully read all the one shot previous year questions and son, work day and night and keep your enthusiasm high, your seniors have done it, you guys can also do it and many children will also do it, it is said that only the one who accepts defeat loses and a person does not lose until he accepts defeat, if you do not lack in your efforts then nobody can stop you from getting good marks, that's why you will get the link of it also in the description, it is a good book, it has covered previous year questions chapter wise, topic wise and if you are looking for the best batch, then son this is your batch, there are regular live classes whose recordings are also available and still if you have any doubts.
