CHM 202 Quiz - Covalent Bond and Organic Reactions

This CHM 202 Quiz is based on the first slide - Covalent Bond and Organic Reactions.

It covers topics including covalent bonds, intermolecular forces, factors affecting organic reactions (Inductive effect, Mesomeric effect, Resonance effect, Steric effect), and types of organic reactions....etc

This quiz contains 25 multiple choice questions for 20 mins, gotten from last year's exam questions, Wade textbook, and other sources.

Best of luck.
