Which book should I prefer for organic chemistry (questions) OP Tandon or MS Chouhan?

Hello my friend if you want to learn the mechanism of reactions of organic chemistry and you are preparing for JEE/ NEET then just study the material which I mentioned belowNCERT – Class 11+12Op Tandon for JEEYouTube – Physics Wallah Chanel . In this chanel almost every topic of Physics and chemistry has covered upto JEE level.Organic chemistry is all about understanding the mechanisms and then practice a lot of questions so for practice questions I am suggesting you two books you have to solve any one of them but with full concentration.Advanced problem in organic chemistry by MS CHAUHANProblem in organic chemistry by HIMANAHU PANDEY.Revise your notes, NCERT, any one practice book at 3–4 times before your actual examination.Best wishes!!!
