NEET 2024 Physical Chemistry Chapters are a significant part of the NEET UG 2024 Exam. To get a good score in NEET UG aspirants are required to have a strong grip on Chemistry along with Physics and Biology. Medical aspirants must note that recently a few changes have been made to the NEET Syllabus 2024, with some chapters removed and others added or modified. Now, the Chemistry syllabus is divided into Physical Chemistry, Organic Chemistry, and Inorganic Chemistry sections, instead of merely being split into Class 11th and Class 12th topics.
NEET UG is a highly competitive undergraduate-level medical entrance exam in India. As per the new NEET pattern for 2024, there will be 50 Chemistry questions (35 in Section A and 15 in Section B), and candidates must answer 45 (10 out of 15 in Section B). NEET 2024 is scheduled for May 5, 2024. This article provides insight into the important Physical Chemistry Chapters for NEET 2024.
