Chapter 8, Problem 107P

Interpretation Introduction

Interpretation: The function of maleic anhydride in the given equilibrium process should be determined.

Concept introduction:

• Diels–Alder reaction: It is a [4 + 2] cycloaddition reaction between conjugated diene and dienophile which forms a substituted cyclohexene. There are no intermediates in the reaction and it is a one step process.
• Le Chatelier’s principle states that the change in any factor such as temperature, pressure, concentration will cause the equilibrium to shift in such a direction so as to reduce the effect of the change.
