Benzaldehyde

Vedclass · Answer

(C) Aldehydes that do not possess any $\alpha$-hydrogen atoms undergo the Cannizzaro reaction in the presence of a concentrated alkali (like $50\%\,KOH$ or $NaOH$).In this reaction,one molecule of the aldehyde is reduced to the corresponding alcohol,and another molecule is oxidized to the corresponding carboxylic acid salt.Among the given options,Benzaldehyde $(C_6H_5CHO)$ has no $\alpha$-hydrogen atoms,whereas Acetaldehyde,Acetone,and Cyclohexanone all possess $\alpha$-hydrogen atoms.Therefore,Benzaldehyde undergoes the Cannizzaro reaction to form benzyl alcohol and potassium benzoate.

Which of the following,on reaction with $50\%\,KOH$,gives the corresponding alcohol and acid salt?
