It is in syllabus of both though last question was asked in advance from hydrogen in 2014 paper
For mains numerical part of this chapter is more important like estimating h2o2 quantity

From what i know , hydrogen is for jee mains only
Ok bro so I think ncert is sufficient thanks
Are ncert is enough for theory for mains and advanced both for inorganic chemistry you need practice books for inorganic rather than theory books
