Question
The number of compounds from the following which can undergo reaction with ${Br}_{2}/KOH/$ (alcoholic) to give respective products and these respective products can also be obtained separately by Gabriel phthalimide reaction is:
Options
A.5
B.4
C.3
D.6
Solution
Sol. [Key Concept: Count the primary amides ($- {CONH}_{2}$): only these undergo Hofmann bromamide (${Br}_{2}/$KOH) to a primary amine that Gabriel synthesis can also make — three such compounds.]
