An organic compound $\mathrm{A}\left(\mathrm{C}_5 \mathrm{H}_9 \mathrm{~N}\right)$ upon reaction with $\mathrm{Na} / \mathrm{Hg} / \mathrm{C}_2 \mathrm{H}_5 \mathrm{OH}$ gives compound B . B reacts with $\mathrm{NaNO}_2 / \mathrm{HCl}$ at 274 K to form C with quantitative liberation of $\mathrm{N}_2$ gas. B also reacts with Hinsberg's reagent to form a compound which is soluble in alkali. Identify compound B.

Identify the product $(\mathrm{Y})$ formed in the given reaction and the name of the reaction where $(\mathrm{X}) \rightarrow(\mathrm{Y})$.

Choose the correct statement:

An organic compound $[\mathrm{X}]$ (molecular formula- $\mathrm{C}_5 \mathrm{H}_{11} \mathrm{NO}$ when reacted with $\mathrm{Br}_2$ / aq. NaOH yielded $[\mathrm{Y}]$ which reacts with $\mathrm{CHCl}_3$ and Ethanolic KOH to produce a foul smelling compound. Compound $[\mathrm{Y}]$ also reacts with HONO to produce Butan-1-ol with liberation of $\mathrm{N}_2(\mathrm{~g})$. Identify [X].
