Chapter: Chemistry Overview

Chemistry is the branch of science concerned with the substances of which matter is composed, the investigation of their properties and reactions, and the use of such reactions to form new substances.
For Neet preparation , understanding about chemistry is difficult task ,so one aspirant should provide important focus on this subject. Well with help of video lectures and the notes provided by the Kaysons Education is best way to deal with the concept of organic and inorganic chemistry.
NEET Chemistry comprises three major sections of organic, inorganic and Physical Chemistry

Organic Chemistry carries more weightage in chemistry than other sub discipline.
Organic Chemistry is a sub-discipline of Chemistry that deals with carbon compounds. It is that branch of Chemistry that many people hate (they say, it’s a lot of mugging up). But, once you know the basics (Hybridization, Isomerism, H-Bonds, Carbonization and Sigma and Pi-bonds) of the subject well, preparation can be done easily. Organic Chemistry shares 28% weightage of the total number of questions.
You have to learn the basic concepts in organic chemistry after which you can solve the problems and reactions.

Tips for Organic Chemistry

You have to remember a few basic things, after which the preparation for the subject is easy. It is said that you have to mug up everything, but if you had clear the basic concepts of the reactions then you don’t have to do this.
The basic things, you have to remember are:
• atomic and molecular orbital, their interactions
• VSEPR theory and their various applications
• dπ-pπ back bonding and anti-bonding orbital
• how pi and sigma orbital are formed
• other concepts of basic bonding theory
• hybridization
• formal charges and how to find them.
You should also be aware of atomic and chemical properties of halogens and nitrogen group. The concepts of acidity, the basicity of acids and basics like Lewis type, Bronstead type, etc. and knowledge of their salts like NaCl, KCl, etc. fetch you great points. Learning the properties of AlCl3, HgCl2, concepts of charge density, atomic structure and stoichiometric knowledge is a must. And if you have some knowledge of the Kinetic Theory of Gasses, things like activation energy, how catalysts work and some basic concepts of thermodynamics, then the subject is as easy as a cakewalk. You must know the names of various compounds that constitute reagents, substracts etc. Practice through the variety of questions of Organic Chemistry to make command over it.

IUPAC Nomenclature:

This is one of the significant hurdles while preparing Organic Chemistry. Some basic nomenclatures like aromatic rings with substitutes, fused rings & Spirocyclic compounds, oxiranes & oxetanes and functional groups should be prepared well.


The students whose concepts are clear they feel that ,it’s one of the easiest section of Chemistry and you can solve this section in very less time than other two sections. Best way to prepare for Inorganic Chemistry is to practice through the NCERT book. No numerical or any formula based problems are asked from this subject, which saves the time for solving other questions. You need to go thoroughly from the basic concepts. Don’t try to solve the questions directly.

Inorganic Chemistry
• Periodic Properties of Elements
• Block Elements – d, f, p, s
• Co-ordination Compounds
• Chemical Bonding
• Hydrogen Bonding

Organic Chemistry
• Basic principles
