Solution Steps

Step 1: Identify the Reactants and Reagents

The reactants are an epoxide (a three-membered cyclic ether) and ethylmagnesium bromide (EtMgBr), which is a Grignard reagent.

Step 2: Understand the Reaction Mechanism

Grignard reagents react with epoxides to open the ring and form alcohols. The nucleophilic carbon in the Grignard reagent attacks the less substituted carbon in the epoxide, leading to ring opening.

Step 3: Determine the Product

The ethyl group from the Grignard reagent will add to the less substituted carbon of the epoxide, and the oxygen will be protonated to form an alcohol.

Final Answer

The product of the reaction is compound II, which is 1-ethylcyclohexanol.
