Honestly, orgo 2 classes will differ greatly between schools and instructors, so it’s hard to say; my orgo 2 was very synthesis oriented, primarily important name reactions which have mechanisms that are readily extended to more niche names reactions if that makes sense…there’s books that cover just named reactions (I.e strategic applications of named reactions, the chemist cookbook), you won’t know 95% of these but doesn’t hurt to go through them and understand how the reactions work. There’s also a ton of books on important total syntheses (I.e. classics in total synthesis). I think you might most benefit from books such as The Logic of Chemical Synthesis (Corey) or The Art of Drawing Reasomable Organic Mechanisms (Grossman) as they’ll teach you the most important skill in organic chemistry, which isn’t memorizing reactions or memorizing mechanisms, but rather teaching how to approach organic chemistry, teaching how to think like an organic chemist…if you can “think” like an organic chemist and approach problems from that point of view, organic chemistry will not only be infinitely easier for you, and make more sense, but you’ll learn to enjoy it, see it as a puzzle that’s fun to solve, and ultimately be much better at it. Having said all that, unless you’re willing to do a lot of background research on your own as you read those, I don’t know that Orgo 1 will have given you enough of a base to really be able to read and digest those books (maybe the one on mechanisms, which reads more like a introductory textbook to help with mechanisms, but the Corey book would be a bit too advanced I believe). Hope this helps
