Alcohols, Phenols And Ethers

Question

Which of the following undergoes reaction with 50% sodium hydroxide solution to give the corresponding alcohol and acid?

Phenol

Benzoic acid

Butanal

Benzaldehyde

Solution

Benzaldehyde

A + NaOH → alcohol + acid
Thus, it is Cannizzaro reaction
A is thus aldehyde without H at alpha - carbon
(as C₆H₅CHO.HCHO)
2C₆H₅CHO + NaOH → C₆H₅CH₂OH + C₆H₅COONa
