An organic compound `(A)` on reduction gives compound `(B)` which on treatment with `CHCI_(3)` and alcoholic `KOH` gives compound `(C )` which on hydrolysis gives aniline but on compound `(C )` which on hydrolysis gives aniline but on catalytic reduction gives n-methylaniline The compound `(A)` is .

Options

A. nitrobenzene
B. nitromethane
C. Methylamine reacts with nitrous acid and liberates `N_(2)` from aqueous solution .
D. aniline

Answer

A

Explanation

Since N-methyl aniline is a `2^(@)` amine `C` must be an isocyanide which implies that `B` is `1^(@)` aromic amine and hence `A` is nitrobenzene
