JEE Main Inorganic Chemistry Weightage 2025 : NTA is going to release JEE Main Syllabus 2025 for Physics, Chemistry, and Mathematics subjects on the official website of NTA. JEE Main Chemistry Syllabus 2025 includes three sections i.e., Section A Physical Chemistry, Section B Inorganic Chemistry, and Section C Organic Chemistry.
Candidates must know the section-wise weightage of JEE Main Chemistry Syllabus 2025 to prepare accordingly. JEE Main Inorganic Chemistry Weightage 2025 is updated in this article. JEE Main Inorganic Chemistry includes topics such as Classification of Elements and Periodicity in Properties, p-Block Elements, D and F Block Elements, and Coordination Compounds. As per the students, Inorganic Chemistry is the easiest part of JEE Main Chemistry Syllabus 2025.JEE Main Inorganic Chemistry Weightage 2025 | |
