The more reactive dienophile of the given has to be predicted. Concept Introduction: Diels-Alder reaction: A conjugated diene reacts with a compound containing a carbon-carbon double bond. It is a cycloaddition reaction, where two reactants form a cyclic product. Rule: The stabilities of carbocation are, Benzyl cation = allyl cation = 3 ∘ carbocation > 2 ∘ carbocation > 1 ∘ carbocation > methyl cation > vinyl cation

(a)

Interpretation Introduction

Interpretation:

The more reactive dienophile of the given has to be predicted.

Concept Introduction:

Diels-Alder reaction:

A conjugated diene reacts with a compound containing a carbon-carbon double bond. It is a cycloaddition reaction, where two reactants form a cyclic product.

Rule: The stabilities of carbocation are,

Benzyl cation = allyl cation = 3∘carbocation > 2∘ carbocation > 1∘ carbocation > methyl cation > vinyl cation
