NCERT Solutions for class 12 Chemistry | All Chapters

NCERT Solutions for class 12 Chemistry

Download NCERT Solutions for class 12 Chemistry all chapters given in separate PDF. NCERT exercises and intex questions solution are given separately.

12 Chemistry Solutions – All Chapters

Chapter 1: The Solid State

Point Defects – The defects caused by missing or misplaced atoms or ions in the crystal. Schottky, Frenkel and interstitial defects are stoichiometric defects.

Chapter 2: Solutions

Raoult’s Law – The vapour pressure of a solution is equal to the product of mole fraction of the solvent and its vapour pressure in pure state.

Chapter 3: Electrochemistry

A galvanic cell is represented by writing the anode (where oxidation occurs) on the left hand side and cathode (where reduction occurs) on the right hand side.

Chapter 4: Chemical Kinetics

Chemical Kinetics – The branch of chemistry which deals with the study of reaction rates and their mechanism. The rate of change of concentration of any of the reactant or product with time at any particular moment of time is known as Rate of reaction.

Chapter 5: Surface Chemistry

A colloidal solution in which there is great affinity between the disperse phase and the dispersion medium is called Lyophilic Solutions. A colloidal solution in which there is a little affinity between the disperse phase and the disperse medium is called Lyophobic solutions.

Chapter 6: General Principles and Processes of Isolation of Elements

Refining is essential for getting pure metal which is depends upon the nature of metal and gangue. Hardness of steel is depend upon the percent of carbon.

Chapter 7: The p – Block Elements

Each noble gas element, with its saturated shell electronic configuration, marks the completion of the period in which it is placed. They are chemically inert, but can be made to combine by coordination or by excitation of electrons (in case of large atoms).

Chapter 8: The d – Block Elements

The characteristic properties of transition metals result from the fact that in these metals the differentiation electron enters into penultimate shell d-orbital. Thus the (n-1)d configuration of the metal and its ion plays important part in giving the observation set of properties to the metal or its ion.

Chapter 9: Coordination Compounds

Formation of coordination compounds results from the Levis acid property of the metal ions with high e/r ratio. Shapes of these compounds decided by the electronic configuration of metal ion and hence the type of hybridisation which the metal ion undergoes during coordination of the ligands.

Chapter 10: Haloalkanes and Haloarenes

Tri-idomethane (Iodoform) is used as an antiseptic and this nature is due to iodine that is liberates. However because of its very unpleasant smell, it has now been replaced by better antiseptic. It is used in the manufacturing of pharmaceuticals.

Chapter 11: Alcohols, Phenols and Ethers

Lucas Test – A solution of ZnCl2 prepared in concentrated HCl is called Lucas regent. If this reagent is added to a specimen of alcohol then if white turbidity appears immediately it is tertiary alcohol. This turbidity is due to the formation of alkyl chloride in general.

Chapter 12: Aldehydes, Ketones and Corboxylic Acids

Acetone does not undergo polymerisation reactions rather two and three molecules of acetone combine together in the presence of dy HCl gas to form mesityl oxide & phorone.

Chapter 13: Amines

In common system, the cyanides are named as alkyl or aryl cyanide whereas in IUPAC system they are named as alkane or arene nitriles. In common system, they are also named on the basis of the acid produced by their hydrolysis replacing ‘ic acid’ by ‘onitriles’.

Chapter 14: Biomolecules

Niacin is nicotinic acid and niacin amide nicotinamide. Both contain a pyridine ring system. Niacin is obtain form fish, yeast, beans and peanuts. Milk and fish contain only a low account of this vitamins.

Chapter 15: Polymers

Chapter 16: Chemistry in Everyday Life

Artificial Sweeteners are the chemical compounds which give sweetening effect to food and enhance its odour and flavour. A very popular sweetening agent is saccharin.

Concepts of Organic Chemistry By Himanshu pandey

Hello Guys : In today's post I have Brought up a very helpful book for Organic Chemistry. Book Name : Concepts of Organic Chemistry By Himanshu pandey
New Pattern Advanced Problems in Organic Chemistry: For - JEE and All Other Engineering Entrance Examinations 5th Edition is authored by Himanshu Pandey and published by G.R. Bhatla Publications. It is a comprehensive book for Organic Chemistry. In addition, the book helps in making a clear understanding of organic chemistry concepts for the entrance exams. This book is essential for candidates applying for JEE and other entrance exams.

About Himanshu Pandey :

Himanshu Pandey is an author by profession. He has authored books likeThe genetic manipulation in plants and Advanced Problems In Organic Chemistry For JEE & All Other Engineering Entrance Examinations.

Reader Review :
Himansu Pandey is a book usually prescribed for IIT-JEE/JEE MAINS. I've done most of the book and I feel like their segregation for levels isn't very apt. What I mean is, that difficulty in my opinion isn't the criteria for segragation so you can't quite know which one to proceed with.Also, as you have witnessed level 2 being easier in one topic, I'm sure as you proceed with the others you'll notice the reverse. I agree that the book is pretty good but it is also a waste of time if you're a 2017 aspirant. At this time, you should do your coaching books properly and thoroughly. If you're done with those then I give you a go-ahead to solve Himanshu Pandey but then again there's the dilemma of the levels?So I just you to start with any of the levels and do 60–70 questions per topic. This would take a lot of time as the questions are quite tricky. Also, remember not to attempt integer type etc.
It's all about managing time at the end. So, if you can do that go -ahead!

The Name of the book is Solomens and Fryhle .


Here I am going to share some some important tips that will help you will in studying the Organic chemistry and  remember that Organic Stuffs is too easy to understand. You just need patience and the mechanism of every process. So the tips are-
1. Keep up with your studying everyday never let yourself get behind, or
better be a little ahead of your Teacher.

2. Study topics in small units, and be sure that you understand each and every
section before you go on to the next. Because of its cummulative nature.

RC Mukherjee | IIT JEE BOOKS



Hi Friends, In this post i am going to provide you the questions of one of the best books of physical chemistry, that is called RC MUKHERJEE.


Yes, it is one of the best book for physical chemistry which has a lot of  problems from low to high level based on JEE MAIN AND JEE ADVANCED. This book is generally recommended by most of the coaching class chemistry teachers. It's theory is too good. But  currently I am going to provide you the questions, as practice is much more necessary than theory part. And i really want to say you guys sorry as due to a lot of theory part i am not been able to publish it fully as due to this i am posting the questions which are of very tough level from this book for you to solve and if you want theory part too, then i will publish a seperate post for that part. For now you can practice questions from here by downloading this book. So i am very pleased to provide you this edition of RC mukherjee book.

As per the changing pattern of IIT-JEE every year, some changes in the presentation of the text and changes in problems have been made. My goal is to provide you the best books available with quality content. The presentation of heat and thermodynamics have been modified. The consistent presentation helps to modify the concepts of thermodynamics. As the central concepts of chemical reactions are too good,other topics such as thermodynamics, kinetics have also been improved. You will find the follwing chapters questions in this book- mole concept, problems based on equations stiochiometry, gas analysis, atomic and molecular weight, problems on titration. Electrolysis and electrolytic conductance, estimation of organic compounds in various forms, atomic structure,properties of gases, liquid solutions,  chemical- equillibrium and thermodynamics, ionic equillibrium, kinetics, electromotive forces,cells, oxidation and reduction and balancing of reduction- oxidation reactions. I must want to say that if you follow this book for solving numericals then surely you can achieve higher marks in chemistry section because there is just formula to use in solving numerical at that time and as physical chemistry is easier as compared with organic and inorganic there is not do much that you have to memorize in you brain. You can also see that mostly they ask in physical chemistry are numerical questions which are generally very easy only you have to be faster and quicker in solving and doing calculations. And the most important chapters of physical chemistry are heat & thermodynamics, ionic equillibrium, chemical kinetics, mole concept, stiochiometry etc. If you prepare these chapters then surely your jee rank will boost and will provide you a good score and a good rank.
Some tips for students-
1.This book has been written in the language of the moles, as the concept of mole is a essential factor in physical chemistry, understood it deeply. And related to its titration too which will be also helpful from your school point of view.
2. Almost all the fundamental principles have been provided before the introduction of new concepts, study them throughly.
3. A large number of selective problems have been provided, study them and try to mix them with other related concepts and then try to solve them.
4. Practice a lot as much as you can. Try to solve out atleast previous 10 years question papers and if i say they are so easy if you have understood all the concepts and formula properly. And practice atleast 10-15 different kind of hard level mixed questions per day, they will boost your confidence and also clear your doubt's where you got stuck and always remember why you stuck there.
So friends that's all for this post. If you have any query related to this book or want to suggest to post a book or any other query, then please email me or comment in the comment box. I will surely try to do my best to resolve your query. Till then keep practicing regularly, have a smile on face and lead yourself towards excellence and success. And remember the aim-IITJEE.
