Predict the major product of the following reaction:

1. The starting material is an $\alpha ,\beta$ -unsaturated ketone.2. Grignard reagents (${\text{CH}}_3\text{MgBr}$) typically undergo nucleophilic addition to the carbonyl carbon of ketones.3. Since the reagent is in "excess," the ketone group is completely converted.4. The first mole of ${\text{CH}}_3\text{MgBr}$ adds to the carbonyl to form an alkoxide, which upon hydrolysis with ${\text{H}}_3{\text{O}}^{+}$ yields a tertiary alcohol while maintaining the double bond.The major product is 2-phenyl-4-methylpent-3-en-2-ol.
