OK, so you're considering which book to get for 2 semester intro organic chemistry. Just buy the assigned text for the course, right? well, maybe.
You should know there are 2 basic approaches to the teaching of organic chem: The functional group approach and mechanism approach. By far, the former is much more commonly used and the way organic chem has been taught for decades. Problem is, this approach promotes tedious memorization and you can be overwhelmed by the volume. Also, most organic chemists don't think in terms of functional groups. They understand their subject by organizing/systematizing reactions according to mechanism and reaction type as governed by a few basic principles.
The number of books that support this mechanism approach are few in number. They are (this list may be incomplete):
Organic Chemistry by Marye Anne Fox, James K. Whitesell (ISBN 0763721972)
Organic Chemistry by Clayden, Greeves, Warren, Wothers
A Guidebook to Mechanism in Organic Chemistry (6th Edition) by Peter Sykes
A Primer to Mechanism in Organic Chemistry by Peter Sykes
Organic Chemistry by Joseph M. Hornback (ISBN 0534389511)
----------------------------------------------
For the the functional group approach:
Just based on its sheer size and completeness, the best book has to be Organic Chemistry (now in its 6th Edition) by Morrison & Boyd (ISBN 0136436692). It's the gold standard by which all other functional group books are judged.
2nd best is probably Organic Chemistry by G. Marc Loudon (ISBN 0195119991).
All the rest - Ege, McMurry, Solomons, Wade, Carey, Bruice, Vollhardt, Maitland Jones Jr., Streitwieser/Heathcock, Brown/Foote - they're just clones of one another. The exceptions might be Bruice and Jones Jr. which employ a quasi-mechanism/functional group approach.
--------------------------------------------
For those of you who want to start off with "just the facts" before tackling these organic tomes try: "Organic Chemistry: A Short Course" by Hart/Craine/Hart/Hadad now in its 12th edition.
The 2 books by David R. Klein are also recommended: "Organic Chemistry I as a Second Language: Translating the Basic Concepts" and "Organic Chemistry II as a Second Language: Second Semester Topics".
Another good intro: The Nuts and Bolts of Organic Chemistry: A Student's Guide to Success by Joel Karty
For the lab portion get "The Organic Chem Lab Survival Manual: A Student's Guide to Techniques" by James W. Zubrick
Check out my listmania "good organic chemistry books from simple to intermediate" for other organic books.
P.S. I should really mention Solomons since I am "reviewing" his book. It's very average and middle-of-the road. there. done.
disclaimer: I used the 3rd edition of Solomons years ago. Why does this book need 9 (and now 10) editions? The teaching of organic chem. hasn't fundamentally changed in a long time and certainly not in the past 20 years.
