2) Mole concept, Avogadro number. 
3) Chemical formulae, Empirical and Molecular formulae 
4) Balanced chemical equations; Balancing redox equations by ion electron and oxidation number methods
5) Calculations, based on mole concept, involving common oxidation-reduction, neutralization, and displacement reactions.
Refer Stoichiometry chapter. But take the help of your teacher while reading it for the first time.
6) Concentration terms: mole fraction, molarity, molality and normality. Refer Solutions chapter.
2) Gaseous and liquid states 1) Gas laws and Absolute scale of temperature;
2) ideal gas equation; 
3) Deviation from ideality, van der Waals equation; 
4) Kinetic theory of gases, average, root mean square and most probable velocities and their relation with temperature;

4) Qualitative quantum mechanical picture of hydrogen atom, Schrodinger's wave equation, shapes of s, p and d orbitals; Radial probability curves.
5) Electronic configurations of elements (up to atomic number 36); Aufbau principle; Pauli’s exclusion principle and Hund’s rule; 
It is really important to start the journey into chemistry at this chapter. You should lay your foundations here. You need to learn electronic configurations to understand chemical properties.
3.2) Chemical bonding 

 

1) Orbital overlap and covalent bond; 
2) Hybridization involving s, p and d orbitals only; 
3) Orbital energy diagrams for homo-nuclear diatomic species;
4) Hydrogen bond; 
5) Polarity in molecules, dipole moment (qualitative aspects only);
6) Valence Shell Electron Pair Repulsion (VSEPR) model and prediction of shapes of molecules (linear, angular, triangular, square planar, pyramidal, square pyramidal, trigonal bipyramidal, tetrahedral and octahedral).
Atoms tend to bond with others in many ways to form millions of molecules that will make this life beautiful. In this chapter you will learn how to understand the properties of atoms and molecules based on the electronic interactions and structures. 
PHYSICAL CHEMISTRY    
4) Energetics 1) First law of thermodynamics; Internal energy (E), work and heat (q), pressure-volume work; Enthalpy (H), Hess’s law; Heat of reaction, fusion and vaporization; 
2) Second law of thermodynamics; Entropy (S); Free energy (G); Criterion of spontaneity.
Refer thermodynamics chapter from NCERT textbook or any book with applications in chemistry.
5.1) Chemical equilibrium 1) Law of mass action; Equilibrium constant (K), 
2) Le Chatelier’s principle (effect of concentration, temperature and pressure); 
3) Significance of ΔG and ΔG° in chemical equilibrium; 
NCERT textbook is more than sufficient. However you need to solve more problems on yourself.
5.2) Ionic equilibrium 4) Acids and bases (Bronsted and Lewis concepts);
6) pH; 
7) common ion effect;
8) buffer solutions; 
6) Hydrolysis of salts;
5) Solubility product .
Same as above. Solving problems from equilibrium chapters is really challenging and fun. 
6) Electrochemistry 1) Electrochemical cells and cell reactions; Standard electrode potentials; Nernst equation and its relation to ΔG; Electrochemical series, emf of galvanic cells; 
2) Faraday’s laws of electrolysis; 
3) Electrolytic conductance, specific, equivalent and molar conductivity, Kohlrausch’s law; Concentration cells.
You can appreciate chemistry when you find something interesting like this chapter. Try to generate electricity by some kind of chemical reaction. That is the motto. 
7) Chemical kinetics 1) Rates of chemical reactions; 
2) Factors affecting rate;
3) Rate law; Order and molecularity of reactions; 
4) Rate constant, its units;
5) First order reactions, integrated rate equations; 
6) Temperature dependence of rate constant (Arrhenius equation).
You can refer kinetics topics on this site. Learn why some reaction take initiation like in your preparation.
8) Solid state 1) Classification of solids, crystalline state;
2) seven crystal systems (cell parameters a, b, c, α, β, γ), 
3) close packed structure of solids (cubic), packing in fcc, bcc and hcp lattices; Nearest neighbours, ionic radii, simple ionic compounds,
4) point defects.
Very nice explanation is given in NCERT textbook.
9) Solutions & Colligative properties  1) Raoult’s law; Molecular weight determination from lowering of vapour pressure, 
2) Elevation of boiling point and depression of freezing point.
Everyone has problems, but chemists have solutions.
10) Surface chemistry 1) Adsorption - only elementary concepts (excluding adsorption isotherms); 
2) Colloids: types, methods of preparation and general properties;
3) Elementary ideas of emulsions, surfactants and micelles (only definitions and examples).
See why sometimes superficial reading is so important. 
11) Nuclear chemistry 1) Radioactivity: isotopes and isobars; Properties of α, β & γ rays;  2) Kinetics of radioactive decay (decay series excluded), carbon dating; Stability of nuclei with respect to proton-neutron ratio; 
3) Brief discussion on fission and fusion reactions.
This chapter is not included in the chemistry syllabus by CBSE or most of the state boards. Please refer physics textbooks.
Inorganic chemistry    
Isolation/preparation and properties of non-metals 1) Boron (B), silicon (Si), nitrogen (N2), phosphorus (P), oxygen (O2), sulphur (S) and halogens (F2, Cl2, Br2, I2); 
2) Properties of allotropes of carbon (only diamond and graphite), phosphorus and sulphur.
Huh! They say "only". But they include everything while asking questions. It is IIT! man. I______I_____________T! That is why most of us are finally into real estate business.
Preparation and properties compounds 1) Oxides, peroxides, hydroxides, carbonates, bicarbonates, chlorides and sulphates of sodium, potassium, magnesium and calcium; 
2) diborane, boric acid and borax;

9) hydrogen sulphide, oxides, sulphurous acid, sulphuric acid and sodium thiosulphate; 
10) hydrohalic acids, oxides and oxyacids of chlorine, bleaching powder; 
11) Xenon fluorides.
Read s-block and p-block (main group elements) completely. Most of us do no like this part. Really it is boring if you read in passive style.
Transition elements (3d series) 1) Definition, general characteristics, oxidation states and their stabilities, color (excluding the details of electronic transitions) and calculation of spin-only magnetic moment; 
2) Coordination compounds: nomenclature of mononuclear coordination compounds, cis-trans and ionization isomerisms, hybridization and geometries of mononuclear coordination compounds (linear, tetrahedral, square planar and octahedral).
This is one of the favorite chapter for IIT professors. Sometimes I suspect, whether I am reading NCERT textbook for +2 students or an undergraduate textbook like Housecroft? It is equally useful to PG students.
     

 PREPARATION (OR) PLAN OF ACTION FOR IIT JEE

Most common question asked by students is  "How do I prepare for IIT JEE exam?"

Just follow these steps:

* Read and understand NCERT or state text books and solve the questions in them.

* Solve previous year and third party model question papers in a logical manner.

* Participate in the group discussions.

IF YOU STILL HAVE QUESTIONS RELATED TO PREPARATION PLEASE GO THROUGH THE FREQUENTLY ASKED QUESTIONS SECTION.

SUGGESTED BOOKS & WEBSITES FOR IIT JEE CHEMISTRY

You should first start your IIT JEE preparation by reading NCERT textbooks.

 FREQUENTLY ASKED QUESTIONS

* How do I prepare for IIT JEE Chemistry part?

Already this is discussed. Please go through the section: Plan of action for IIT JEE CHEMISTRY paper.

* What are the important topics in chemistry?

For me, chemistry is not divided like that. Every topic is related to other. So try to capture the heart of chemistry. However you can start with easy and fundamental topics in which you are interested and slowly go for relatively harder topics.

If you feel something is not easy to assimilate or boring, just try the application part.

* Is it possible to crack IIT JEE exam without coaching?

Yes. Why not? You need to do smart work. I am giving you the following two important suggestions.

* Read thoroughly, the NCERT textbooks. Try to understand the topics and solve all the questions given at the end of each chapter on your own. First try yourself. If you wont get the answer then you can consult any expert or discuss it in the group. Only go for the prepared solutions as a last resort. Also solve previous year question papers and other model papers available from various sources. 

* Very important part of your study must include discussions. If you are shy to discuss with others, you can join my chemistry forum at facebook and join discussions. This is the best way to express yourself freely without any fear and learn from others. It is actually fun to learn through online discussions. You will learn different ways of tackling a problem.

* Do you provide study material for IIT JEE chemistry?

Actually lots of study material is available in the market. I too prepared some topics and put them on this website. So you can go through them freely.

* Where do I get solved previous year JEE question papers?

Again there are so many sources in the market. Buy them from any book stall or try online. 

* How do I purchase solved question papers from your site?

You can pay me by remitting the requisite amount into my bank account either at your nearest branch or through NEFT. For more details you can mail me at:

contact

* Do you send printed papers to my postal address?

No. I will only provide you with downloadable soft copy in the ebook format. You can save this on your hard disk or take the printouts.
