Vedclass · Answer

(C) The reaction involves the hydration of an aldehyde in the presence of an aqueous acid.Aldehydes exist in equilibrium with their hydrate form,known as a geminal diol.For the given aldehyde $Ph_2CH-CHO$,the addition of water across the carbonyl group results in the formation of the geminal diol $Ph_2CH-CH(OH)_2$.This hydrate is the major product $(A)$ in the equilibrium mixture.

$Ph_2CH-C(=O)H \xrightarrow{\text{aqueous acid}} (A) (81\%) + \text{enol} (2\%) + \text{aldehyde} (17\%)$. Product $(A)$ of the above reaction will be:
