Question

The major product of the reaction is

• A.
• B.
• C.
• D.

Answer 1

The Correct Option is D

To determine the major product of the given reaction, let's analyze the provided structure and reaction conditions.

The starting material is a bicyclic compound with a double bond and axial hydrogens. The reaction is carried out at 150°C, indicating a possibility of a thermal rearrangement, particularly a Cope rearrangement or something similar due to the high temperature.

The compound is likely undergoing a conformational change leading to a more stable arrangement. The most feasible pathway is an internal rearrangement that relieves strain, possibly involving a ring expansion or contraction that forms a stable product.

In this scenario, the major product would involve the elimination of strain through a rearrangement to give a more favorable, stable product. This involves the migration of the double bond and hydrogens to achieve conjugation or relief of angle strain.

Conclusion: Based on the available options, the image above represents the correct major product of the reaction. This product is the result of the necessary rearrangement to achieve a lower energy state.
