The given reaction involves the thermal opening of a cyclopropane ring to form an intermediate, which can occur through either a conrotatory or disrotatory mechanism. The reaction is a part of the electrocyclic reactions, governed by Woodward-Hoffmann rules. The key factor is the thermal condition which influences the type of rotation.

Understanding Conrotatory vs. Disrotatory Opening:

The conrotatory process involves the simultaneous rotation of orbitals in the same direction during ring opening, whereas in the disrotatory process, the orbitals rotate in opposite directions. According to Woodward-Hoffmann rules, under thermal conditions:

• For a 4n electron system (even number of electron pairs like in cyclobutene), the allowed mode is disrotatory.
• For a 4n+2 electron system (odd number of electron pairs, typically pi systems), the allowed mode is conrotatory.

Application to Given Reaction:

In the given reaction, the cyclopropane system under thermal conditions and electron count indicates a conrotatory process consistent with molecular orbital interactions.

Conclusion:

Since the question involves a thermal reaction of a cyclopropane ring, the conrotatory opening matches the conditions provided.

The intermediate formed through conrotatory opening

Therefore, the correct statement is:

•  is formed through conrotatory opening of X.
