Important Topics for NEET Chemistry

Important Topics for NEET Chemistry

NEET chemistry syllabus can be divided into 3 parts i.e Organic, Inorganic, and Physical Chemistry. The weightage of questions asked from each section is almost the same every year. 

  • NEET Physical Chemistry: It’s the numerical section of NEET Chemistry.
  • NEET Organic Chemistry: From this section, you must focus on memorizing the names of various compounds that constitute reagents, subtracts, etc.
  • NEET Inorganic Chemistry: This section is considered the easiest section of NEET Chemistry.

Candidates must note that NEET 2023 syllabus will be reduced. As the classes will start late this year, candidates will not get enough time to cover all the important topics hence the authorities have decided to curtail NEET 2023 syllabus. Check NEET Chemistry Syllabus

Important Topics based on all the 3 sections of chemistry are mentioned in the table below:

Organic Chemistry Inorganic Chemistry Physical Chemistry
Amines D Block Elements Atomic Structure
Organic Compounds Containing Oxygen Classification of Elements & Periodicity Mole Concept & Stoichiometry
Environmental Chemistry Chemical Bonding and Molecular Structure Redox Reactions & Electrochemistry
