potential useful links for students planning to enroll in organic chemistry

Arrow Pushing in Organic chemistry (~ 7 MB; ~ 300 pages, where only ~ half is content; the remainder are answers to problems)

initial impression: seems to have a systemic development of concept

Everything you need to know about mechanism (~ 1 MB; ~ 13 pages)

initial impression: like use of electron polarity map, but there are gaps in its content

links to additional resources at UT organic chem course website

initial impression: no opinion, since did not explore links
