Answer 1

Correct Answer - A
`underset(1^(@)"amide")(CH_(3)CONH_(2))rarrunderset(2^(@)"amine")(CH_(3)NH_(2)`
To convert a primary amide into a primary amine with one carbon atom less, we need to perform Hofmann bromamide reaction
`CH_(3)CONH_(2)+Br_(2)+4NaOHrarr`
`CH_(3)NH_(2)+Na_(2)CO_(3)+2NaBr+2H_(2)O` .
