Solution
The correct option is A CH3 CH2 COOH
Br2/KOH is the reagent for Hoffmann bromamide reaction. In this reaction amide is coverted primary amine.
Thus, 'C' is an amide.
Carboxylic salt on heeating gives amide.
Thus, 'A' is a carboxylic acid which on reaction with NH3 forms salt.
Product of hoffmann bromamide reaction is ethamine. Thus, 'A' is ethanoic acid.
