What is the end product in the following sequences of operations;

\mathrm{Acetamide}\xrightarrow{{{\mathrm{P}_2}{\mathrm{O}_5}}}A\xrightarrow{{4\mathrm{H}}}B?

View answer and explanation

Correct option: B

{\mathrm{C}_2}{\mathrm{H}_5}\mathrm{N}{\mathrm{H}_2}

Option B (

{\mathrm{C}_2}{\mathrm{H}_5}\mathrm{N}{\mathrm{H}_2}

) is correct because acetamide undergoes dehydration with P2O5 to form acetonitrile, which is then reduced to ethylamine.
