A student performed analysis of aliphatic organic compound ' $\displaystyle X$ ' which on analysis gave $\displaystyle C=61.01 \%$, $\displaystyle \mathrm{H}=15.25 \%, \mathrm{~N}=23.74 \%$. This compound, on treatment with $\displaystyle \mathrm{HNO}_2 / \mathrm{H}_2 \mathrm{O}$ produced another compound ' $\displaystyle Y$ ' which did not contain any nitrogen atom. However, the compound 'Y' upon controlled oxidation produced another compound ' $\displaystyle Z$ ' that responded to iodoform test. The structure of ' $\displaystyle X$ ' is :
