Which one of the following on treatment with 50 % aqueous sodium hydroxide yields the corresponding alcohol and acid?

Step-by-step solution

According to Cannizzaro's reaction. 2 C ₆ H ₅ CHO + NaOH 50 % NaOH C ₆ H ₅ COONa + C ₆ H ₅ CH ₂ OH Related Theory Aldehydes containing no -hydrogen atom on warming with 50 % NaOH or KOH undergo disproportionation i.e. self oxidation reduction known as Cannizzaro's reaction. Caution Aldehydes that contains alpha hydrogen atoms are not involved in Cannizzaro reaction.
