Vedclass · Answer

(B) The reaction of $m$-chlorobenzaldehyde with concentrated $NaOH$ is a Cannizzaro reaction. Aldehydes that do not contain any $\alpha$-hydrogen atoms undergo self-oxidation and reduction (disproportionation) in the presence of a concentrated base. In this reaction,one molecule of $m$-chlorobenzaldehyde is oxidized to the corresponding salt of the carboxylic acid (sodium $3$-chlorobenzoate),and another molecule is reduced to the corresponding alcohol ($3$-chlorobenzyl alcohol). The reaction is: $2 	ext{ } m	ext{-Cl-C}_6	ext{H}_4	ext{CHO} + 	ext{NaOH (conc.)}$ $ightarrow m	ext{-Cl-C}_6	ext{H}_4	ext{CH}_2	ext{OH} + m	ext{-Cl-C}_6	ext{H}_4	ext{COONa}$.
