An organic compound [A] with molecular formula $\text{C}_3\text{H}_7\text{NO}$ forms compound [B] on heating with $\text{Br}_2$ and KOH. Compound [B] on heating with $\text{CHCl}_3$ and alcoholic KOH produces a pungent smelling compound [C]. Compound [B] on reacting with $\text{C}_6\text{H}_5\text{SO}_2\text{Cl}$ forms compound [D] which is soluble in alkali.
Write the structures of compounds [A], [B], [C] and [D].

[A] is propanamide, $\text{CH}_3\text{CH}_2\text{CONH}_2$
[B] is ethylamine, $\text{CH}_3\text{CH}_2\text{NH}_2$ (formed by Hofmann bromamide degradation)
[C] is ethyl isocyanide, $\text{CH}_3\text{CH}_2\text{NC}$ (carbylamine test product with pungent smell)
[D] is N-ethylbenzenesulphonamide, $\text{C}_6\text{H}_5\text{SO}_2\text{NHC}_2\text{H}_5$ (soluble in alkali due to acidic hydrogen on nitrogen)
