`CH_3-C -= CH underset(1% HgSO_4)overset(40% H_2SO_4)to A overset("Isomerisation")to CH_3-underset(O)underset(||)C - CH_3`
Structure of 'A' and type of isomerism in the above reaction are respectively.

A

Prop-1-en-2-ol, metamerism

B

Prop-1-en-1-ol, tautomerism

C

Prop-2-en-2-ol, geometrical isomerism

D

Prop-1-en-2-ol, tautomerism

Text Solution

Verified by Experts

The correct Answer is:
D
`underset("Propyne")(CH_3-C -= CH) overset(40% H_2SO_4)underset(1% HgSO_4)to underset("Prop-1-en-2-ol (A)")(CH_3-overset(OH)overset(|)C=CH_2) overset("Tautomerization"to underset("Acetone")(CH_3-overset(O)overset(||)C-CH_3)`
Prop-1-en-2-ol (A) and acetone are tautomers.
