Physical, Organic, and Inorganic concepts for NEET Chemistry Preparation 2020  

by Rohan

The NEET chemistry examination syllabus is divided into physical, organic, and inorganic chemistry. Chemistry is indeed a scoring subject if students prepare thoroughly. The NEET chemistry examination comprises 180 marks for 45 questions of the total 720 marks for 180 questions of the NEET examination. 

It is thus important that one knows the key aspects for better NEET Chemistry Preparation.

36% of the chemistry examination weightage goes to inorganic and physical chemistry, and 29% is organic chemistry. At times, the three different topics of chemistry have similar weightage. 

To better your preparation, it is important to understand your strengths and weaknesses in the three parts of chemistry and then decide how to prepare best and approach the examination to score maximum marks. A foolproof preparation strategy is what can give students an edge to do better in the examination.

Important topics for NEET chemistry examination

Let us first list down the topics under each of the three chemistry sections.

Based on the past year’s question papers, here are the topics on which students were assessed.

Organic Chemistry

  • Organic Compounds Containing Oxygen
  • Environmental Chemistry
  • What is Nuclear Stability
  • Amines
  • Basic Principles of Organic Chemistry
  • Hydrocarbons and their substituents
  • Biomolecules
  • F Block Elements
  • Polymers

Inorganic chemistry

  • What is Mass Defect
  • Classification of Elements & Periodicity
  • D Block Elements
  • States of Matter & Solutions
  • Hydrogen and S Block Elements
  • Practical Chemistry
  • Chemical Bonding and Molecular Structure
  • P Block Elements
  • Coordination Compounds

Physical chemistry

  • Atomic Structure
  • Redox Reactions & Electrochemistry
  • Thermochemistry & Thermodynamics
  • Equilibrium
  • Nuclear Chemistry & Chemical Kinetics
  • Surface Chemistry
  • Mole Concept & Stoichiometry

Physical Chemistry

Physical chemistry is the numerical part of the chemistry examination. It is important to be thorough with the concepts to attempt the physical chemistry section. To solve the numerical, you need first to know the concept attached to it. While preparing, list the formulas and practice physical chemistry questions daily to score good marks in this section.

Organic Chemistry 

In the organic chemistry section, students should understand the equations and memorise them. There are reactions and formulas in this section. It is important to by-heart the compounds that constitute the subtracts and reagents. Practices several questions from the reference books to gain mastery over organic chemistry.

Inorganic Chemistry 

This is the easiest section in NEET chemistry which makes it a section that you should attempt. It takes very little time to complete this section. Most questions asked will be a direct application of formulas. It is important that you understand the formula and not mug it up.

Tips for scoring better marks in NEET chemistry examination

  • Start with a proper strategy on how you will begin the preparation. Planning is important to perform well in the NEET examination. Create small, achievable goals. This will let you monitor the progress well. Have a weekly study plan and set weekly targets to push you to meet your preparation deadlines.
  • Most of the time, the NEET chemistry questions will be a direct pick from some reference book. So it pays to practice as many books as possible. 
  • However, do not jump from one to the other. Get the best NEET examination reference books and complete one thoroughly before you move to the next.
  • It is also important that you practice several mock question papers with a time limit. The past NEET question papers are a good start. These help you evaluate your preparation and understand your level to figure out the topics you need to revise on. You also get to understand the exam pattern and judge your speed.
  • Practising past question papers does not throw you a surprise on your NEET chemistry exam day.

You should incorporate the above tips to fare well in the examination. Also, understand the topic-wise mark distribution so you can plan your preparation accordingly.

Topic weightage in NEET chemistry examination

Here is the number of questions that were asked in the previous year NEET Chemistry examination. It pays to understand these and the topic weightage, so you know which topics need more practice.

It is important to gain a thorough understanding of the concepts rather than do rote learning. Understand the formulas and reactions because if you comprehend something well, it becomes easy to remember. Solve as many questions as you can. 

Take several mock tests under a mock exam environment. This will let you gauge your speed and highlight the topics that you need to prepare more. Keep a rough book where you can jot down the important points and formulas during the preparation, so you need to brush on them before your final exam date.

You must go through the syllabus and weightage of each topic to prepare better and appear for the NEET Chemistry examination with complete confidence.
