What’s CH 320N about?
Primarily for premedical, predental, life sciences, and pharmacy majors. The development of organic chemical functional group reactivity, reaction mechanics, with analogous aqueous transformations in biochemical settings. Only one of the following may be counted: Chemistry 320N, 328N, 329C. Three lecture hours a week for one semester.
Prepare for class
- Functional group reactivity
- Reaction mechanisms
- Biochemical parallels
Review · Review how to identify a nucleophile and an electrophile in a mechanism.
Self-check · Why does the carbonyl carbon attract the nucleophile?
Show the answer
Oxygen pulls electron density toward itself. The carbon is partially positive and can accept an electron pair.
