Answer & Solution

Correct Answer

(C) potassium cyanide, \(\mathrm{KCN}\)

Step-by-step Solution

Detailed explanation

In order to prepare \(1^{\circ}\) amine from an alkyl halide with simultaneous addition of one \(\mathrm{CH}_2\) group in the carbon chain. The reagent used as a source of nitrogen is KCN. Chemical transformation can be shown as,
