Chapter 22.1, Problem 1P

Interpretation Introduction

a)

Interpretation:

The enol tautomer of Cyclopentanone shown is to be given.

Concept introduction:

A carbonyl compound with a hydrogen atom on its α carbon atom is in equilibrium with its corresponding enol isomer. The spontaneous inter-conversion between two isomers usually with the change in position of a hydrogen is called tautomerism. The individual keto and enol isomers are called tautomers.

To give:

The enol tautomer of cyclopentanone shown.

Interpretation Introduction

b)

Interpretation:

The enol tautomer of Methyl thioacetate shown is to be given.

Concept introduction:

A carbonyl compound with a hydrogen atom on its α carbon atom is in equilibrium with its corresponding enol isomer. The spontaneous inter-conversion between two isomers usually with the change in position of a hydrogen is called tautomerism. The individual keto and enol isomers are called tautomers.

To give:

The enol tautomer of Methyl thioacetate shown.
