Reddit reviews Chemistry: A Molecular Approach (4th Edition)

Yeah that's a confusing title. I know Gen Chem uses these books, and I've seen them around. Author name matches your screen as well. Don't feel obligated to shell out for the 4th ed, 3rd or maybe even 2nd would be fine. Also you'll need an online access code, which sometimes come with an ebook included. Do a bit more research first for that, and don't be afraid to email your instructor!
