JEE Advanced levelSingle correct optionDifficulty 3 of 3co206

Compound A ( $C X_{2} H X_{4} O X_{2}$ ) liberates $CO X_{2}$ from aqueous $NaHCO X_{3}$ . A reacts with $SOCl X_{2}$ to give B; B reacts with excess $NH X_{3}$ to give C; C is heated with $P X_{2} O X_{5}$ to give D; D is hydrogenated over $Ni$ to give E. E is

A $CH X_{3} CH X_{2} OH$
B $(CH X_{3} CH X_{2}) X_{2} NH$
C $CH X_{3} CONHCH X_{3}$
D $CH X_{3} CH X_{2} NH X_{2}$

Answer: D

A is ethanoic acid. B is ethanoyl chloride, C is ethanamide, D is ethanenitrile, and catalytic hydrogenation of the nitrile gives the primary amine E,

CH X_{3} CH X_{2} NH X_{2}

, ethanamine.
