Hi aspirant,

Chemistry in general is considered to be the most scoring part of JEE main examination. Physical Chemistry is somewhat easier than other two parts because it is mostly numerical based basic ideas of concepts and formula can give you good marks. Talking about the most scoring chapters in physical chemistry that has to be surface chemistry because the concepts are very easy and just practicing the previous year problems would give you very good marks. Apart from this solid state is also quite easy as most of the portion is theory based. Solutions have numerical based upon the basic formula and is considered easy by students. Periodic classification of elements is a theory based chapter and having knowledge of various concepts can fetch you good marks.

Hope it helps!
