Question

In the electrocyclic ring-opening reaction shown below, which answer best describes the product mixture?

• A. The product will consist primarily of A
• B. The product will consist primarily of B
• C. The product will consist primarily of C
• D. A and C are both major products

Answer 1

The correct option is B The product will consist primarily of B

Pericyclic reaction is a type of organic reaction where in the transition state of the molecule has a cyclic geometry and the reaction are usually rearrangement reaction.

Electrolytic reaction is a type of pericyclic rearrangement where the net result is one $\pi$ bond being converted into sigma bond or vice versa.

So the answer is (B).
