Question

An organic compound $$A$$ containing nitrogen, on acid catalysed hydrolysis produces a water-soluble organic compound $$B$$ and a gaseous compound $$C$$. When methyl magnesium bromide is slowly added to $$A$$ in 1 : 1 ratio and hydrolysed, it produces a compound which can be obtained by dry distillation of the calcium salt of $$B$$. The compound $$A$$ is:


A
N-methylmethanmide
loader
B
N-ethylmethanamide
loader
C
acetonitrile
loader
D
N, N-dimethylmethanamide
loader
E
methylisocyanide
loader

Solution

The correct option is B acetonitrile
Acetonitraile($$ CH_{3}-C\equiv N $$) on acid catalyzed hydrolysis produces acetic acid which is water soluble organic compound and a gaseous compound NH$$ _{3} $$.
When methyl magnesium bromide is slowly added to A in 1:1 ratio of hydrolysed, it produces a compound acetaldehyde which can be obtained from dry distillation of calcium salt of acetic acid i.e. calcium acetate.
