Question
**Question**: Which compound is the dominant product of the reaction below? **Reaction Equation**: - Starting compound: A ketone with a six-membered aromatic ring (phenyl group) and a three-membered saturated carbon chain with an oxygen double-bond. - Reagents: \( \text{CH}_3\text{CH}_2\text{OH} \) (ethanol) and \( \text{H}_2\text{SO}_4 \) (sulfuric acid). **Products**: 1. **Compound A**: A secondary alcohol where the hydroxyl group (\(-OH\)) is attached to the carbon adjacent to the phenyl group. An ethoxy group (\(-OCH_2CH_3\)) is connected to the other carbon. 2. **Compound B**: Features a hydroxyl group on the middle carbon of the chain and an ethoxy group on the end carbon, with the phenyl group on the opposite side. 3. **Compound C**: An isomer where the ethoxy group is attached to the second carbon and the hydroxyl group is on the terminal carbon. 4. **Compound D**: Contains a hydroxyl group on the third carbon with an ethoxy group on the middle carbon. **Multiple Choice Options**: - Compound A - Compound D - Compound B - Compound C _Select the compound that is the dominant product of this reaction._

Expert Solution
Step 1

In that reaction ethanol(CH3CH2OH) will act as a nucleophile at first and attack the less hindered site in the epoxide . And after the attack ( - O- ) will form . Then in presence of Acid ( here sulfuric acid) ,the oxide ion will be protonated. The corresponding compound A will be major product.
