Step 1
Identify the Product X from the First Reaction
Answer
In the first reaction, the hydration of propene (CH₂=CH-CH₃) occurs with water (H₂O). This results in the formation of propan-2-ol (also known as isopropanol or X). The reaction can be represented as:
ightarrow ext{CH}_3 ext{CHOHCH}_3$$Step 2
Determine the Reaction of X with Acetic Acid
Answer
The next step involves the reaction of propan-2-ol (X) with acetic acid (CH₃COOH). This is a condensation reaction to form an ester. The product Y from this reaction would be:
ightarrow ext{CH}_3 ext{COOCH(CH}_3)_2 + ext{H}_2 ext{O}$$ This gives us isopropyl acetate (which corresponds to option B).Step 3
