Chemistry20233 marksShort answer
An organic compound ‘A’ on treatment with aq. $\text{KCN}$ produces compound ‘B’. Compound ‘B’ on reduction with $\text{Na}/\text{C}_2\text{H}_5\text{OH}$ gives compound ‘C’ with molecular formula $\text{C}_2\text{H}_7\text{N}$. Compound ‘C’ reacts with $\text{NaNO}_2$ and $\text{HCl}$ to form compound ‘D’. Compound ‘D’ on treatment with acetic acid in presence of conc. $\text{H}_2\text{SO}_4$ produces a sweet smelling compound ‘E’.
(i)[2.0]
Identify the compounds ‘A’ to ‘E’.
