Most Important Chemistry Topics For IIT JEE Preparation

IIT JEE Preparation Tips

IIT JEE is a national level examination that serves as the gateway for admission to different Engineering Colleges. It is regarded as one of the toughest exams in the country, both in terms of competitiveness, and the syllabus it carries. Chemistry is regarded as the toughest of the three subjects, and most of the students consider it a daunting task to understand the subject. It is necessary to prepare all the chapters; however, here are a few important topics that need to be given extra importance.

 1.   Organic Chemistry

This is the part of chemistry that usually carries a very high weightage of marks. The scope of organic chemistry is very wide, and it is difficult to understand. Hence, it is necessary to have clear basics. A solid foundation is necessary if you wish to have a clear understanding of Organic Chemistry. There are named reactions that are an integral part of Organic and should be given utmost priority. Apart from that, have a good understanding of Isomerism, Hydrocarbons, Alcohols, Phenols, Ethers, Aldehydes, and organic Reagents is necessary. The structure, formations, and properties are of sheer importance.

2.   Periodic Table

It is the single most important topic that is comparatively easier to understand and has been taught ever since the 6^th standard. You are expected to learn the periodic table up to atomic number 36. Learn it from left to right and from top to bottom as well. It is also useful in all of Inorganic Chemistry. Understand the s-block, p-block, f-block, and first transition elements. Although learning the atomic number is also helpful, and proves to be a time-saver, you can figure that out by the electronic configuration and the position of the element. You also need to learn the atomic weights of a few elements, which will be necessary for solving some questions.

 

3.   Chemical Kinetics

A branch of Physical Chemistry, Chemical Kinetics, deals with the influence of experimental conditions on the rate of the reaction and the reaction’s mechanism. Understand Integration and solve linear differential equations. Apart from that, focus on the types of reaction (elementary and complex), mechanism of complex reactions, and factors affecting reaction rates. Ultimately to get a grasp of Chemical Kinetics, you need to understand these concepts and practice.

 

4.   Redox Reactions

When there is an electron transfer between the two reactants, it is called a redox reaction. An in-depth understanding of what Redox reactions are is necessary for the exam. Several examples of redox reactions happen in front of us every day, including processes like Photosynthesis, Corrosion, and combustion. Learn how to make these equations and the different methods of balancing these equations. Also, remember the oxidizing agents and reducing agents. A basic understanding of the periodic table is necessary to ace this topic.

 

5.   Chemical Bonding

Chemical Bonding is the formation of bonds between two or more atoms, ions, or molecules, resulting in the formation of chemical compounds. Learn the dot structure of different elements, types of chemical bonds, their order, and their moments. Also, I have a good knowledge of what Hybridization is and how it works. The properties of different bonds, their strengths, and formations are important to understand.

 

6.   Chemical Thermodynamics

The study of the relation between heat and work during a change in the state or the chemical reaction. Four entities should be in focus: internal energy, entropy, enthalpy, and Gibbs free energy. Understand what a system is and the components in it. Also, study the principles of thermodynamics to understand this topic well. It is not very difficult to get a grasp of thermodynamics and is an easy to score topic.

 

7.   Co-Ordination Chemistry

The study of compounds that have a central atom, surrounded by molecules or anions, which are called Ligands. These ligands are attached to the central atom by a dative bond, in which both the electrons are supplied by the same atom of the ligand. Mostly these compounds are metals, and the bonds are also known as co-ordination bonds. This is also easy to understand and an easy to score topic in Chemistry.

Although Chemistry has been touted to be difficult to understand, it is a rather simple affair. Yes, there are more exceptions in chemistry than the whole world combined. However, if the basic concepts of chemistry are clear, it is not very difficult to understand and can help you score some good marks in the exam.
