Concept explainers
(a)
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,
