Chapter 21, Problem 30P, 23.29 Draw enol tautomer(s) for each compound. Ignore stereoisomers.

Expert Solution

Interpretation Introduction

(a)

Interpretation: Enol tautomer(s) of the given compound is to be drawn.

Concept introduction: Tautomers are the isomers which differ only in the position of the hydrogens and electrons of electronegative element, generally oxygen. There is no change in the carbon skeleton of the compound. This phenomenon which involves simple proton transfer in an intramolecular fashion is known as tautomerism.

The very common example of tautomerism is Keto-enol tautomerism. It can be acid or base catalysed.
