CH_(3)-C-=CH underset(1%HgSO_(4))overset(40%H_(2)SO_(4))toA overset("Isomerisation")to CH_(3)-underset(O)underset(||)(C)-CH_(3) Structure of 'A' and type of isomerism in the above reaction are respectively.

Answer»

Prop-1-en-2-ol, metamerism
Prop-1-en-1-ol, tautomerism
Prop-2-en-2-ol, geometrical isomerism
Prop-1-en-2-ol, tautomerism

Solution :`underset("PROPYNE")(CH_(3)-C-=CH) underset(1%HgSO_(4))OVERSET(40%H_(2)SO_(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. THUS, option (d) is correct.
