Vedclass · Answer

(C) $1$. Decarboxylation of $C_6H_5COONa$ with soda lime $(NaOH/CaO)$ gives $X = C_6H_6$ (Benzene).$2$. Gattermann-Koch reaction of benzene with $CO/HCl$ in the presence of anhydrous $AlCl_3$ gives $Y = C_6H_5CHO$ (Benzaldehyde).$3$. The reaction of benzaldehyde with concentrated $NaOH$ is a Cannizzaro reaction.$4$. In the Cannizzaro reaction,$C_6H_5CHO$ undergoes disproportionation to give $A = C_6H_5CH_2OH$ (Benzyl alcohol,the reduction product) and $B = C_6H_5COONa$ (Sodium benzoate,the oxidation product).

Consider the following sequence of reactions.
$C_6H_5COONa$ $\xrightarrow[\Delta]{NaOH/CaO} X$ $\xrightarrow[\text{Anhy. } AlCl_3]{CO/HCl} Y$ $\xrightarrow[NaOH]{\text{conc. }} A + B$.
If $A$ is the reduction product of $Y$,what is $B$?
