- Diels–Alder reaction of a monosubstituted diene (such as CH2=CH–CH=CHOCH3) with a monosubstituted dienophile (such as CH2=CHCHO)gives a mixture of products, but the 1,2-disubstituted product oftenpredominates. Draw the resonance hybrid for each reactant, and use thecharge distribution of the hybrids to explain why the 1,2-disubstitutedproduct is the major product.a.
