Predict the product 'B' in the sequence of reaction `HC equiv CH overset (30% H_(2) SO_(4))underset(Hg SO_(4)) to A overset (NaOH) to B`

A

`CH_(3)`COONa

B

`CH_(3)` COOH

C

`CH_(3)`CHO

D

`CH_(3) - underset(OH) underset(|)(CH) - CH_(2)`CHO

Text Solution

Verified by Experts

The correct Answer is:
D
Oxymercuration of ethyne gas with `HgSO_(4)//H^(+)` gives ethanal which undergoes aldol condensation with NaOH to give `hat(a)`-hydroxybutanal
