Hello all, I recently received a job doing pharmaceutical sales. So I need to brush up on some of chemistry (took it 7 years ago, don't remember much). My girlfriend is a chemist so I can use her for help if I get stuck on something I don't get, but besides that, what is the best intro book to use? I am reteaching myself calculus now, so by the time I get to the chem book I will know calculus, but don't remember anything from physics or calculus unfortunately, so treat it as something a highschooler could self teach with. I bought Pauling's "general chemistry" for $10, but have heard some say it is not the best intro book. I need something that is very intuitive...that can kind of help me get "why" what the stuff means/is, not something that can help me pass a test (as I will not be tested) or just rigorously help me equate things. Now, I am also not an idiot and don't need to be fully babied either. Do you think with no prior knowledge, I can use Paulings book and maybe suppliment it with khanacademy and my girlfriend, or should I get something like chem for dummies and read that before pauling? i also have Introductory chemistry: concepts and crtiical thinking by corwin.
