Step-by-step solution

Dienes and Dienophiles

Dienes are compounds that contain two C=C bonds, and dienophiles are those that contain one C=C bond.In the Diels-Alder reaction, these compounds joined together, forming a Diels-alder product.

Diene and Dienophile in (a)

In this compound, the diene contains two double bonds, and the dienophile has one functional group COCH₃; when these are joined together, it results in the formation of the desired product.

Diene and Dienophile

Diene and Dienophile in (b)

In this compound, the diene contains two methoxy (-OCH₃) groups, and the dienophile has one functional group COOCH₂CH₃; when these are joined together results in the formation of the desired product.

Diene and Dienophile

Diene and Dienophile in (c)

In this compound, the diene will be the furan ring, and the dienophile has one functional group CN; joining together results in the formation of the desired product.

Diene and Dienophile

Diene and Dienophile in (d)

In this compound, the diene will be the cyclohexene ring containing two double bonds, and the dienophile has two COOCH₃ groups; when these are joined together results in the formation of the desired product.

Diene and Dienophile

Diene and Dienophile in (e)

In this compound, the diene contains one methoxy (-CH₃) group, and the dienophile has four CN groups; when these are joined together, it forms the desired product.

Diene and Dienophile

Diene and Dienophile in (f)

In this compound, the diene will be a cyclopentadiene ring, and the dienophile has two ketone groups in the furan ring; when these are joined together results in the formation of the desired product.
