Answer
In this reaction, propene (CH₂=CH–CH₃) reacts with water (H₂O) in a hydration reaction. The product X will be isopropanol (CH₃CHOHCH₃) after the addition of water across the double bond.

Answer
The isopropanol (X) can react with acetic acid (CH₃COOH) in an esterification reaction to form isopropyl acetate (Y). The structure of Y is CH₃COOCH(CH₃)₂, which corresponds to option B: CH₃COOCH₂CH₃.
