NEET levelSingle correct optionDifficulty 1 of 3co066

Benzaldehyde is treated with concentrated NaOH at room temperature. The products formed are

Aphenylmethanol and sodium benzoate
B2-hydroxy-1,2-diphenylethanone
Ctoluene and sodium benzoate
Dsodium benzoate only

Answer: A

Benzaldehyde has no alpha-hydrogen, so it undergoes Cannizzaro disproportionation. One molecule is reduced to

C X_{6} H X_{5} CH X_{2} OH

and another is oxidised to

C X_{6} H X_{5} COO X^{-} Na X^{+}

.
