Most scoring topics for JEE mains- Chemistry

JEE Mains is one of the most significant exams that take place in India every year. The exam is a challenge for every engineering aspirant in the country and requires utmost dedication and focus in order to be cracked. The examination is scheduled for April 15-16, 2018. Admit cards for JEE Mains are now available on the official website of the exam i.e at

JEE mains- Chemistry

Generally, students perceive Physics or Mathematics as the most scoring subject in the examination however, little do they know that with almost no calculations, Chemistry is the easiest of them all. The questions are pretty direct and theory based. There is no room for guessing or approximation. Due to lack of calculations, silly mistakes can also be avoided.

Furthermore, some topics in Chemistry syllabus issued by CBSE for JEE Mains are even easier than others and in turn can help you improve your score. Below we have mentioned 10 topics which are not only an assured part of the paper, but also the easy and scoring at the same time.

1. Some Basic Concepts of Chemistry

This topic is probably the easiest topic from the entire syllabus of JEE Main. As the name suggests, the topic focuses on the basic knowledge of Chemistry and the concepts related to it. Questions are based on mole concept, S.I. Units, the concept of the atom, molecule, element & compound, chemical equations, physical quantities and their measurements in Chemistry and more.

2. Environmental Chemistry

Environmental chemistry is also an easy and scoring topic in Chemistry. Questions are based topics that are a part of general discussion among students. The questions usually revolve around pollution and its types- soil, water, particulate, tropospheric, atmospheric and stratospheric. Water Pollution. Students must also know about greenhouse effect, global warming, and acid rain.

3. Chemistry in Everyday Life

Chemistry in everyday life is further divided into topics such as cleansing agents, chemicals in food and chemicals in medicines. It is further divided into three broad sub-topics. Candidates must know the following things about each topic.

  • For Cleansing Agents, students must learn about the properties and cleansing actions of soaps and detergents.
  • For Chemicals in Food, students should know about the preservatives, artificial sweetening agents, etc. and their examples.
  • For Chemicals in Medicines, students should have knowledge regarding the antacids, antiseptics, tranquilizers, antifertility drugs, antibiotics, etc. and their properties in addition to 1-2 examples as well.

Students can refer to their NCERT textbook for this information.

4. States of Matter

This topic focuses on the classification of matter into its three states- solid, liquid and gaseous. The students need to have knowledge about their respective properties, the law’s related to each state of matter, such as Dalton’s law of partial pressure. Though it may seem too much to remember, the reason it is easy in comparison to others is that these are something that the students have been taught since 6th-7th standard.

5. Classification of Elements & Periodicity in Properties

This topic is a little difficult as compared to rest in the list. However, this is easier to prepare compared to many in the whole syllabus. While preparing these topics, the students need to focus on the following aspects:

  • Modern periodic law
  • The present form of the periodic table.
  • S, P, D and F block elements
  • Electron gain enthalpy, valence, oxidation states and chemical reactivity.

Students are taught this in class 11th and 12th as basics, making an easier topic to prepare. Moreover, the added benefit of preparing this particular topic is that there are other similar topics in the syllabus that can be use this topic as a base.

6. General principles and Process of Isolation of Metals

Many students would be shocked and confused to see this topic on the list and they are probably right. But the reason for including this topic here is because they would have to study it for their boards as well. Students will have to prepare the following topics:

  • Modes of occurrence of elements in nature, minerals, and ores.
  • Thermodynamic and electrochemical principles involved in the extraction of metals.
  • Steps involved in the extraction of metals.
  • Refining with special reference to the extraction of Al, Cu, Zn, and Fe.

7. Chemical Kinetics

Chemical Kinetics is one topic which most of the students find quite interesting and easy to understand. The topic is divided into further sub-topics that are mentioned below:

  • The rate of a chemical reaction, factors affecting the rate of reactions: concentration, temperature, pressure, and catalyst.
  • Elementary and complex reactions, order and molecularity of reactions, rate law, rate constant and its units.
  • Differential and integral forms of zero and first order reactions, their characteristics and half-lives, the effect of temperature on the rate of reactions.
  • Arrhenius theory, activation energy and its calculation, collision theory of bimolecular gaseous reactions (without derivation).

8. Hydrogen

For this topic, students should once again refer to their NCERT textbooks as all the information for this topic is provided there in a manner that would help them to learn. While reading, the students should focus on the following sub-topics:

  • Hydrogen as a fuel.
  • The position of hydrogen in periodic table, isotopes, and preparation.
  • Its properties and uses.
  • Hydrogen peroxide- its structure, preparation, reactions, and uses.
  • Classification of hydrides – ionic, covalent and interstitial
  • Physical and chemical properties of water and heavy water.

9. Chemical Bonding

This particular topic is a part of class 11th Chemistry syllabus and students can refer to NCERT book while preparing the same.  The focus is on Ionic Bonding and Covalent Bonding.

Students need to know about the formation, concepts and properties of bonding. Learning the same can be helpful in solving almost every question.

10. Polymers

This particular topic may seem to be difficult but the fact is that the questions based on it are not. Students need to focus on the following sub topics to ace in this segment of the examination:

  • classification of polymers
  • general methods of polymerization
  • Natural and synthetic rubber and vulcanization
  • Some important polymer such as polyethylene, nylon, polyester, and Bakelite; with emphasis on their monomers and uses.

It is advised to refer to Class 12th NCERT textbook to prepare for the same.

Hope this article was helpful and enables you to ace the Chemistry section of your JEE Main paper.
