1.	Which one of the following has the slowest esterification rate?(a) Primary(b) Secondary(c) Tertiary(d) All the mentionedThe question was posed to me in an interview for job.This intriguing question comes from Esterification by Organic Acids in portion Esterification of Unit Processes
Answer» Right choice is (c) Tertiary The explanation is: It is stated that the more branched the carbon chain of the alcohol and the nearer the branches are to the HYDROXYL group, the slower will be its ESTERIFICATION and the lower the limit. These effects are DUE to steric HINDRANCE to the approach of the alcohol to the acid molecule.
