Chapter 20, Problem 89IP

Interpretation Introduction

Interpretation: Among the given structures, the one that is not an intermediate in the given reaction has to be found.

Concept Introduction:

Intermediate: It is a molecular entity that will be formed from the reactants and reacts further with the reactant to give the desired products. It exists for a life time appreciably longer than a molecular vibration.

The given reaction is:

The following observations are made:

• It is clearly shown that the given reaction is a decomposition reaction since heat energy is involved. So ring opening had taken place in the product shown.
• The involvement of ${\text{H}}_{\text{3}}{\text{O}}^{\text{+}}$ indicates that the reaction is an acid hydrolysis reaction.
