NEET Chemistry Syllabus 2020

NEET Chemistry Syllabus comprises of topics included in class 11th and 12th Organic, Inorganic and Physical Chemistry. This section is scoring for many students as all the compositions, chemical reactions, chain reactions, mechanisms goes mostly on the basics. Several times, the questions asked in NEET examination are picked directly from the concepts taught in the NCERT textbooks. Also, past few years’ question paper trends suggest that the students are examined in this section by similar kind of questions with a fluctuating difficulty level.

Before starting any preparations, the students are suggested to know all the topics included in NEET Chemistry Syllabus 2020. Preparing the concepts based on NEET question paper analysis is one of the best ways to prepare for NEET Chemistry syllabus. The students find it more comfortable in comparison to Biology and Physics. In NEET 2017, the questions asked in the Chemistry section were moderately easy. However, there were some tricky questions that required a strong fundamental base to answer. Given below is the detailed list of all the topics included in NEET Chemistry Syllabus 2020.
