Vedclass · Answer

(B) $1$. The reaction of propan$-1-$ol $(CH_{3}CH_{2}CH_{2}OH)$ with phosphorus pentachloride $(PCl_{5})$ is given by:$CH_{3}CH_{2}CH_{2}OH + PCl_{5} \rightarrow CH_{3}CH_{2}CH_{2}Cl + POCl_{3} + HCl$Thus, $X = POCl_{3}$.$2$. The product $CH_{3}CH_{2}CH_{2}Cl$ reacts with alcoholic $KOH$ upon heating to undergo dehydrohalogenation, forming propene $(Y = CH_{3}CH=CH_{2})$.$3$. Propene $(CH_{3}CH=CH_{2})$ reacts with $HBr$ in the presence of peroxide $((C_{6}H_{5}CO)_{2}O_{2})$ via the anti-Markownikoff addition mechanism to yield $1-$bromopropane $(Z = CH_{3}CH_{2}CH_{2}Br)$.Therefore, $X = POCl_{3}$ and $Z = CH_{3}CH_{2}CH_{2}Br$.

Column-$I$ (Reactants)	Column-$II$ (Type of Reaction)
$(A)$ $C_6H_5NH_2 \xrightarrow{NaNO_2, HX, 273-278 K} C_6H_5N_2^+X^-$	$(i)$ Wurtz-Fittig reaction
$(B)$ $C_6H_5N_2^+X^- \xrightarrow{Cu_2X_2} C_6H_5X$	$(ii)$ Diazotization
$(C)$ $C_6H_6 + 2Na + RX \xrightarrow{\text{dry ether}} C_6H_5R$	$(iii)$ Sandmeyer reaction
$(D)$ $2C_6H_6 + 2Na \xrightarrow{\text{dry ether}} C_6H_5-C_6H_5$	$(iv)$ Fittig reaction

In the following reaction sequence, $X$ and $Z$, respectively, are:
$CH_{3}CH_{2}CH_{2}-OH + PCl_{5} \rightarrow CH_{3}CH_{2}CH_{2}Cl + X + HCl$
$CH_{3}CH_{2}CH_{2}Cl \xrightarrow{alc. KOH, \Delta} Y$
$Y \xrightarrow{HBr, (C_{6}H_{5}CO)_{2}O_{2}} Z$
