Elliott Huffman · Answer 1

A) Three pi bonds break; two sigma bonds and one pi bond form.

Explanation:

Diels Alder reaction -

It is one of the chemical reaction, where the reaction of a substituted alkene and a conjugated diene takes place, is referred to as the diel alder reaction.

Where the substituted alkene is referred to as the dienophile.

Hence, it is also known as diene - dienophile reaction.

The mechanism followed by the reaction is same as for pericyclic reaction, in this reaction, there is breakage of three pi bond and the formation of one pi an two sigma bond.
