Vedclass · Answer

(B) $1$. Benzyl bromide $(C_6H_5CH_2Br)$ reacts with magnesium in the presence of dry ether to form a Grignard reagent,benzylmagnesium bromide $(C_6H_5CH_2MgBr)$,which is $'X'$.$2$. Grignard reagents are strong bases and react with protic compounds like ethanol $(C_2H_5OH)$ to form the corresponding hydrocarbon.$3$. The reaction is: $C_6H_5CH_2MgBr + C_2H_5OH \rightarrow C_6H_5CH_3 + C_2H_5OMgBr$.$4$. Here,$C_6H_5CH_3$ is toluene,which is the compound $'Y'$.

Benzyl bromide on reaction with magnesium in the presence of dry ether gives $'X'$. $'X'$ on reaction with ethanol gives $'Y'$. Then the compound $Y$ is
