`CH_(3) - C -= CHoverset(40%H_(2)SO_(4))underset(1%HgSO_(4))rarrAoverset("isomerisation")rarr`

Structure of A and type of isomerism in the above reaction respectively are

Options

A. Prop-1-en-2-01, metamerism
B. Prop-1-en-1-01, tautomerism
C. Prop-2-en-2-01, geometrical isomerism
D. Prop-1-en-2-01, tautomerism

Answer

D

Explanation

Chemical reaction can be shown as
`underset("Propyne")underset()(CH_(3))-CequivCHoverset(4%H_(2)SO_(4))underset(1% HgSO_(4))rarrCH_(3)-overset(OH)overset(|)C=overset(H)overset(|)CHoverset("keto-enol tautomersim")underset("Prop-1-en-2-01")rarrunderset("Acetone")underset()(CH_(3)-overset(O)overset(||)C-CH_(3))`
[A] is prop-1-en-2-01, Which undergo tautomerism to form acetone.
