Question

Which of the following is formed from the reaction between RNHR’ and R”OCl, where R, R’ and R” are three different alkyl groups?

(a) RNR’COR”

(b) R2NCOR’

(c) R’2NCOR”

(d) R”NR’COR

I got this question by my school principal while I was bunking the class.

This intriguing question originated from Amines Chemical Reactions topic in chapter Amines of Chemistry – Class 12

Answer 1

Correct choice is (a) RNR’COR”

Easiest explanation: This an acylation reaction in which the H atom of RNHR’ gets replaced by the COR” group form R”OCl. Thus, the amide formed consists of three different alkyl groups with two attached to the N atom and one attached to the carbonyl carbon.
