Aspiring JEE is no less than an ambition that can turn your career into a beautiful one if you qualify it. You must be well-aware of this fact that no engineering or architecture student can qualify this exam if he/she is not prepared for the crucial subjects like – Physics, Chemistry & Maths.


IIT JEE Chemistry is a scoring subject if a student handles it carefully! This subject can boost up the selection chances if prepared well. The most favorite thing about Chemistry is that the questions asked in IIT JEE do not make students confound.


Working on the reaction mechanism and mastering the physical and chemical properties of elements and compounds is imperative. Most of the Questions are easier in IIT JEE Chemistry comparatively to other subjects.


In Chemistry 40% questions are easy, 50% are moderate level and 10 % questions are difficult.

IIT JEE Chemistry comprises three important parts-


General Organic Chemistry

 General Inorganic Chemistry

 Physical Chemistry






To provide you a well-drafted plan for all these topics, we have explained them one by one in the blog below. Please go through this guide to have an ultimate learning experience for JEE 2020 Chemistry.



Topic 1: General Organic Chemistry IIT JEE


Organic chemistry plays a vital role in JEE Mains as well as JEE Advanced Exam. It has its own level of understanding! Nomenclature and Isomerism are the main key points that make a complete foot hold on this platform of Organic Chemistry.


Organic Chemistry IIT JEE deals with the scientific study of properties, structures, reactions and mechanism of organic compounds and materials. i.e. the carbon atoms consist in the Matter.


The study of IIT JEE Organic Chemistry includes both - physical and chemical properties of a compound. By using equivalent properties of both, you can master the behavior of organic matter in its pure form.


For example –

1. Petrochemicals are derived from crude oil or petroleum. Fractional distillation separates the raw material into organic compounds according to their different boiling points.

2. Polymers consist of long chains and branches of molecules. Common polymers you encounter every day are organic molecules. for example, Nylon, Polyethylene, PVC etc.



How to Crack Organic Chemistry IIT JEE? Important Topics & Methods to Study them!


If a student makes a way through the concepts of General Organic Chemistry, undoubtedly, he could handle every chemistry reaction and mechanism easily. Every year around 30% questions come from organic chemistry in JEE Exams.


Tip – Use the Flow Chart to Understand the Organic Chemistry Formulas for IIT JEE Reaction Mechanism.






Let’s get started to know how you can score well in IIT JEE Organic Chemistry!


1. Make Skills in Nomenclature

IUPAC Nomenclature is the first & foremost topic you will encounter, but it’s not easy to deal with this topic & move on. For naming the organic compounds you need a logical approach towards it. You must work on the fixed set of Rules to generate the Chemical compound nomenclature mechanism.


2. Learn to deal with Reaction Mechanism

Reaction Mechanism is determined in Chemical Kinematics to deal with reaction order and rate equation of reactants. Make command over reaction steps.


3. Carbon and its Compounds

The hybridization, structure, and shape of carbon compounds need to be noted. The Important concepts of Coal Gases and petroleum and special properties of carbon must be brushed up while you prepare for this subject.


4. Isomerism - The Essential One!

The structural and stereoisomerism are the important points to practice. You must know all the structures related to the compounds and their mechanism covers an important part in Isomerism.


5. Work on Naming Reactions

Naming Reaction is the heart of Organic Chemistry, if you like to deal with Reactions than you can master the Organic Chemistry. List down all the important Naming reactions like SN1 & SN2 reactions, Sand Mayer Reactions, Gattermann reactions, Cannizaro Reactions, Hoffman reactions, Wurtz Reactions etc.


6. Biomolecules, Polymers & Chemistry in Everyday Life

Simplest yet scoring these topics are!

Biomolecule covers an important part in organic chemistry. The RNA and DNA Structures along with special arrangements of glucose and carbohydrates, aldose & ketose groups, these are some of the important topics. The structure of Protein and carbohydrate is important for JEE point of view. Practice structures and reaction chains for this topic.

IIT JEE 2020 Topic 2: General Inorganic Chemistry


Inorganic chemistry for IIT JEE is one of the most important subordinates of chemistry in all aspects, facts, concepts, and its application that consists of the study of Atoms, Elements & their classifications. Inorganic Chemistry Deals with the Behavior & Synthesis of Inorganic & Organometallic Compounds.


Inorganic Chemistry covers a major Part in IIT JEE Exams but students give it less importance as compared to other parts of chemistry. This is because they found it difficult to cover its several properties and the usage of compounds.


Inorganic Chemistry is used in the medicines, fuels, coatings, pigments, as catalyst and many more.


For Example –


1. Chlorine is used in manufacturing of Polyvinyl Chloride such as - Pipes, Clothing, And Furniture etc. & Agriculture Chemicals such as - Fertilizers, Pesticides Insecticides and Soil Treatment). It is widely used in Water Treatment Plant and Sterilization Process.

2. Ammonia a nitrogen source of fertilizers and is one of the major product as an Inorganic compound used in paints, fibers, plastics, foams, explosives and many more.

Inorganic Chemistry Preparation Tips - Master IIT JEE with these Key Points!


Inorganic chemistry for IIT JEE is easier if block elements are taken at high priority.


1. Periodic Table is Essential

Make periodic table your biggest asset. The complete knowledge on the periodic table Metals, Nonmetals, Metalloids their position and the physical and chemical properties is essential. Learn it on fingerprints & master the entire Inorganic Chemistry for IIT JEE 2020 Exam.


 2. Learn Chemical Reactions

A sure-shot formula to get hold on Chemical Reactions is to ‘learn to make it through a Word Equation’. This one is the unbeatable way to score well in inorganic chemistry!

Write each reaction with hand on paper and interrelate the chemicals and their usage.


 3. Make Coordination with ‘Coordination Compounds’

The compounds and their isomerism need a basic understanding on topic. You must try to make practice of arranging the complexes in order of the properties. To enhance your skills, try to understand the electronic configuration of complexes.


 4. The Transitive Elements – Key to Success 

The S, P, D, F blocks play the crucial role in JEE Mains & JEE Advanced Exams. Go through the knowledge of shells and orbitals. Analyze the properties of the elements of each block & their free and combined state in nature.


Tip: All you need to do is learn the Physical and Chemical State, Density, Enthalpy, Melting Point, Boiling Points, Elements Reaction with Oxygen Air and Gases etc.
