Answer:
PETER SYKES is good book which you can definitely refer but you can not entirely rely on this book for your theory as theory in this book containing JEE syllabus is so brief that is hard to understand at once. I personally referred this book rather than SOLOMONS, because I was already in comfort with the organic chemistry and my class notes was enough for me. But our teacher asked us to read this book in general to get better insight on the topics. But if you are not comfortable at the basics itself than this book is not for you definitely, you can use another books like paula yurkaniis bruce, solomons etc. And for questions both MS chouhan and Akshay choudhary is good.
