Chapter 6, Problem 47P

(a)

Interpretation Introduction

Interpretation:

The keto-enol tautomer from the given pairs should be determined.

Concept Introduction:

Enol formation:

Under acidic conditions, alkyne reacts with water to produce an enol which then immediately converts into ketone. For terminal alkynes, there is a need of catalyst which is mercury.

The formed enol and ketone are called keto-enol tautomer.

Tautomerization: It is the process of inter conversion of an enol compound to a ketone compound and therefore the process can also be called as keto-enol tautomerization.
