An organic compound $\mathrm{A}\left(\mathrm{C}_4 \mathrm{H}_9 \mathrm{Cl}\right)$ on reaction with $\mathrm{Na} /$ diethyl ether gives a hydrocarbon which on monochlorination gives only one chloro derivative, then $A$ is
1 tert-butyl chloride
2 sec-butyl chloride
3 isobutyl chloride
4 n-butyl chloride
Explanation:
: An organic compound A is tertiary butyl chloride react with $\mathrm{Na}$ diethyl ether gives a 2, 2, 3, 3 tetra methyl butane which on mono chlorination gives a tert butyl chloride

Acetylene reacting with $\mathrm{HCN}$ in presence of $\mathrm{Ba}$ $(\mathrm{CN})_2$ gives
1 Vinyl cyanide
2 1,1-dicyanoethane
3 1,2-dicyanoethane
4 None of the above
Explanation:
: Acetylene ( $\mathrm{CH} \equiv \mathrm{CH})$ react with $\mathrm{HCN}$ in the presence of $\mathrm{Ba}(\mathrm{CN})_2$ gives vinyl cyanide $\mathrm{CH} \equiv \mathrm{CH}+\mathrm{HCN} \stackrel{\mathrm{Ba}(\mathrm{CN})_2}{\longrightarrow} \mathrm{CH}_2=\mathrm{CHCN}$
