B. Toluene, propylcholoride
C. Phenol, acetone
D. Phenol, acetaldehyde

Answer

To solve the question regarding the reaction of cumene with O2 and H2O in the presence of H+, we will break down the steps involved in the reactions and identify the products (X and Y).

### Step-by-Step Solution:

1. **Identify the Structure of Cumene**:
- Cumene is also known as isopropylbenzene. Its structure can be represented as:
\[ \text{C}_6\text{H}_5\text{C(CH}_3\text{)}_2 \]
- This consists of a benzene ring (C6H5) attached to an isopropyl group (C(CH3)2).

2. **Reaction with O2**:
- When cumene reacts with oxygen (O2), it undergoes oxidation. This reaction typically leads to the formation of phenol and acetone. The reaction can be summarized as:
\[ \text{Cumene} \xrightarrow{O_2} \text{Phenol} + \text{Acetone} \]
- Therefore, the product (X) formed from the reaction with O2 is **Phenol**.

3. **Reaction with H2O in the presence of H+**:
- The next step involves the reaction of cumene with water (H2O) in the presence of an acid catalyst (H+). This reaction also leads to the formation of phenol and acetone:
\[ \text{Cumene} + \text{H}_2\text{O} \xrightarrow{H^+} \text{Phenol} + \text{Acetone} \]
- Thus, the product (Y) formed from this reaction is **Acetone**.

4. **Final Identification of Products**:
- From the above reactions, we can conclude:
- (X) = **Phenol**
- (Y) = **Acetone**

### Final Answer:
(X) is **Phenol** and (Y) is **Acetone**.
