`CH_3 -C-= CH underset(1% Hg SO_4 ) overset(40% H_2SO_4 )to A overset("isomerisation ") to CH_3 - underset(O) underset(||)C-CH_3`
Stucture 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
Chemical reaction can be shown as
`underset("Propyne")(CH_3-C-=CH)underset(1% HgSO_4)overset(40%H_2SO_4)to CH_3-overset(OH)overset(|)C=overset(H)overset(|)(CH) underset("Prop-1-en-2-ol")overset("keto-enol tautomerism")to underset("Acetone")(CH_3-overset(O)overset(||)C-CH_3)`
[A] is , prop −1 − en − 2 − ol , which undergo tautomerism to form acetone.
