Author is Janice Gorzynski Smith and it is the 6th edition. Not much changed with new edition, just some chapters were rearranged. The book has hundreds of practice problems and the solution manual contains detailed answers for all of them. Textbook is loose-leaf, but has been put in a binder and does not have any writing in it. The solution manual is also in perfect condition. Book it perfect for those taking organic chemistry 1 and/or 2, or studying for standardized test such as the MCAT.
