The product (s) obtained by the oxymercuration `(HgSO_4+aq.H_2SO_4)` of but-1-yne are

A

`CH_3CH_2CH_2CHO`

B

`CH_3CH_2COCH_3`

C

`CH_3CH_2CHO+HCHO`

D

`CH_3CH_2COOH+HCOOH`

Text Solution

Verified by Experts

The correct Answer is:
B

The Markovnikovaddition of `H_2O` gives an unstable vinyl alcohol that rearranges to the more stable ketone.
