When the given compound is heated, it undergoes a rearrangement to form an isomer. Identify the major product.

Step-by-step solution

The given reactant is 3-vinyloxycyclohexene, which is an allyl vinyl ether. When an allyl vinyl ether is heated, it undergoes a Claisen rearrangement, which is a thermally allowed [3,3]-sigmatropic rearrangement. In this rearrangement, the following concerted changes occur: 1. The C-O bond between the oxygen and the allylic carbon of the cyclohexene ring breaks. 2. A new C-C bond forms between the terminal carbon of the vinyl group and the -carbon of the allylic system (the other end of the ring's double bond). 3.
