Important topics for JEE Main Organic Chemistry

The pattern of questions asked in Organic Chemistry in JEE Main is not fixed. Questions can be asked at random and therefore, all are important topics for JEE Main 2020. You should prepare the basic and general topics of organic chemistry in detail. These topics include nomenclature, types of reactions, basicity, acidity, etc.

You should be thorough with the named reactions and their mechanism. Questions based on named reactions and mechanism are commonly asked in JEE Main . You should also prepare steps of common chemical reactions. On average, 2-3 questions from the topic – organic synthesis are asked in the exam.

Important topics for JEE Main Inorganic Chemistry

All the topics in Inorganic Chemistry are considered important for JEE Main 2020. All the chapters carry equal weightage in JEE Main. Your basics and the fundamentals should be clear in each and every topic. Inorganic chemistry can help boost your score if you prepare Method of Preparation, Chemical Reactions, uses, etc. of the compounds.

The Elements of the periodic table and Chemical Bonding are the most important topics for JEE Main 2020. These two topics should be on your tips. They are important for building a solid foundation for Inorganic chemistry. Questions asked from Chemical bonding are based on the following topics:

  • Fajan’s Rule & it’s application
  • Shape and Hybridisation
  • Molecular Orbital Theory (where the most important topic is Electronic Configuration)
  • Dipole Moment

Another very important topic for JEE Main in Inorganic Chemistry is Transition elements and coordination chemistry. About three questions are asked from this chapter. Questions are based on topics like Isomerism (Structural, Geometrical, Linkage, Optical Isomerism), Lanthanoid Contraction, Nomenclature and Crystal Field Theory.

Hydrogen and S & P block elements are also among the most important topics for JEE Main. You should be thorough in topics such as structures of various acids like P, S, Cl, N, Nitrogen Oxides, Dimers of Boron and Aluminium, oxides and their acidic-basic structure.

Important topics for JEE Main Physical Chemistry

The most important topic for JEE Main in Physical Chemistry is Mole concept. Many reactions like Redox Reaction are based on Mole concept. So, this topic should be on your tips as this is the basic connect.

Your formulae and basic concepts should be clear in Atomic Structure. Questions are frequently asked from this chapter in JEE Main. Important topics in this chapter are Quantum Numbers, the Wavelength of Electronic Transition and Ionisation Energy.

Gaseous State and Solid state are also important topics for JEE Main 2020. Your fundamentals should be clear on these topics. Frequently asked questions are from topics like van der Waals equation, Kinetic Theory of Gases and Types of Molecular Velocity.

The other topics that carry equal weightage in JEE Main are below:

  • Solutions
  • Electrochemistry & redox Reactions
  • Chemical Bonding and Molecular Structure
  • Chemical Thermodynamics
  • Equilibrium
  • Surface Chemistry
  • Chemical Kinetics
