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-methylmethanamide

B

N-ethylmethanamide

C

acetonitrile

D

N,N-dimethylmethanamide

Text Solution
