$3-$chlorobenzyl alcohol + potassium $3-$chlorobenzoate

(A) The given reaction is a Cannizzaro reaction because the reactant,$3$-chlorobenzaldehyde,does not have any $\alpha$-hydrogen atoms. When treated with $50 \% \ KOH$,it undergoes disproportionation (self-oxidation and reduction). The aldehyde group is oxidized to a carboxylate salt $(COOK)$ and reduced to an alcohol group $(-CH_2OH)$. The products are $3$-chlorobenzyl alcohol and potassium $3$-chlorobenzoate.
