A

Propanal

B

Propyl hydrogen sulphate

C

Acetone

D

Propanol

Text Solution

Verified by Experts

The correct Answer is:
C
`underset("Propyne")(CH_3-C)-=CH+H_2O overset(40%H_2SO_4)underset(1%HgSO_4)rarr`
`underset("(Enol)")(CH_3-underset(OH)underset(|)C=CH_2)overset("rearrangment")underset("tautomerise")rarr CH_3-underset("(Keto)")underset("Acetone"CH_(3))underset(O)underset(||)C-CH_3`
