a)
Interpretation:
Whether the compound shown will be a good dienophile or not is to be predicted.
Concept introduction:
In Diels-Alder reaction, a dienophile reacts with a diene to yield a cyclic adduct. The reaction takes place through 1,4 addition of the dienophile into the diene through a cyclic transition state. These reactions occur rapidly with dienophiles having electron withdrawing substituent groups in conjugation with the double bond.
To predict:
Whether the compound shown will be a good dienophile or not.
