For most of the aspirants, chemistry is the rank decider because it mostly talks about the basics and in comparison to the Mathematics and Physics questions asked in JEE Main, the Chemistry section is more theoretical than calculative which makes it relatively easier for students to score high in this section.
There are many chapters/topics that an aspirant must cover in Chemistry in order to score a better rank. Figuring out the important chapters/topics for JEE Main Chemistry is not a complicated task, and you can identify the same by referring to the previous years question papers of JEE Main.
