CHEM 51A: Organic Chemistry

These videos are part of a 28-lecture undergraduate level course titled "Organic Chemistry" taught at UC Irvine by Professor James S. Nowick in fall 2009. This course covers topics such as bonding and structures, acids and bases, organic molecules and functional groups, alkanes, stereochemistry, organic reactions, alkyl halides and nucleophilic substitution, alkyl halides and elimination reactions, and other various topics. The website for the class is  The course is titled Chem 51A and is part of a three-quarter sequence comprising Chem 51A, Chem 51B, and Chem 51C.
