NEET Chemistry Isomerisation MCQ Question with Solution

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

A

Pro $p^{-1}$ -e $n^{-2}$ -ol, metamerism

B

Pro $p^{-1}$ -e $n^{-1}$ -ol, tautomerism

C

Pro $p^{-2}$ -e $n^{-2}$ -ol, geometrical isomerism

D

Pro $p^{-1}$ -e $n^{-2}$ -ol, tautomerism

Correct Answer

Option D

Detailed Explanation

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