Answer & Solution
Correct Answer
(D) [B]: CH\(_3\[-\)(CH\(_2\))\(_2\]-\)NH\(-\)COCH\(_3\) [C]: CH\(_3\[-\)(CH\(_2\))\(_2\]-\)NC
Step-by-step Solution
Detailed explanation
The molecular formula of the given organic compound is \(C_3H_5N\). Its degree of unsaturation is \(3 + 1 - \dfrac{5}{2} + \dfrac{1}{2} = 2\). The compound undergoes reduction to form [A], which reacts with \(CHCl_3\) and KOH to give a foul-smelling compound [C]. This is the…
