NEET Chemistry Isomerisation MCQ Question

Type: MCQ-conceptual-Medium-Class 11

CH₃—C≡CH 40% H₂SO₄, 1% HgSO₄ → A Isomerisation → CH₃—C—CH₃

Question diagram
A

Prop−1p^{-1}-en−2n^{-2}-ol, metamerism

B

Prop−1p^{-1}-en−1n^{-1}-ol, tautomerism

C

Prop−2p^{-2}-en−2n^{-2}-ol, geometrical isomerism

D

Prop−1p^{-1}-en−2n^{-2}-ol, tautomerism

Correct Answer

Option 4

Detailed Explanation

The reaction involves the hydration of propyne to form propanone (acetone) through tautomerism. The intermediate enol form is prop−1p^{-1}-en−2n^{-2}-ol.
