This book provides problems, with answers and tutorial guidance, on the organic chemistry encountered by students in their last year of A-level and at the beginning of undergraduate courses in Chemistry and Biochemistry. The layout of the book runs parallel with that of the successful Foundations of Organic Chemistry by the same authors. The first three chapters cover basic physical organic chemistry, setting the scene for the mechanistic organic chemistry covered later. The problems are accompanied by useful hints, and the answers with tutorial comments which reinforce the chemical principles involved.
