Are you like me, low and funds, but in need of a textbook for organic chemistry course? You could be, instead ,just looking for a book for some extra reading. How about a FREE textbook which cover most of the topics in organic chemistry? A book that is separated by topic, so you don’t have to download the entire book if you only want to deal with, say, carbonyl reactions. even contains problem sets with answer keys for select problems.Well that is what I found at this site Ochem4free . You can opt to buy the printed version of the textbook, supplementary exercises and solutions to all the problem sets given.
