Starting from propanoic acid, identify the compound Z in the following reactions. P r o p a n o i c a c i d → S O C l 2 X → N H 3 Y → B r 2 + K O H Z
Options
- AC H 3 - C H 2 - B r
- BC H 3 - C H 2 - N H 2
- CC H 3 − C H 2 − C O B r
- DC H 3 - C H 2 - C H 2 - N H 2
Correct answer
B. C H 3 - C H 2 - N H 2
Step-by-step solution
Carboxylic acid form acyl chloride with S O C l 2 , which on further reaction with ammonia gives amide. The amide further undergo Hofmann Bromamide reaction (degradation) to give amine.
