Chapter 11.9, Problem 12P

Interpretation Introduction

Interpretation: Two enols that are formed by the reaction of $\text{pent}-2-\text{yne}$ with ${\text{H}}_{\text{2}}\text{O}$, ${\text{H}}_{\text{2}}{\text{SO}}_4$ and ${\text{HgSO}}_{\text{4}}$ are to be identified. The ketones that are formed by the two resultant enols are to be identified.

Concept introduction: The chemical equilibrium that exists between a keto form of a compound and an enol form of the same compound is known as keto-enol tautomerism. Tautomers refer to these keto and enol forms.
