Answer

To solve the given reaction involving Phenyl Magnesium Bromide (PhMgBr) and deuterium oxide (D₂O), we will follow these steps:

### Step 1: Identify the Reactants
The reactants in the reaction are:
- Phenyl Magnesium Bromide (PhMgBr), which is a Grignard reagent.
- Deuterium oxide (D₂O), which acts as a source of deuterium (D).

### Step 2: Understand the Nature of the Grignard Reagent
Phenyl Magnesium Bromide (PhMgBr) consists of a phenyl group (Ph) with a negative charge (Ph⁻) and a magnesium bromide (MgBr⁺) cation. The phenyl group is highly nucleophilic due to the negative charge.

### Step 3: Reaction Mechanism
When PhMgBr reacts with D₂O, it undergoes an acid-base reaction:
- The phenyl group (Ph⁻) acts as a base and attacks the deuterium in D₂O.
- This results in the formation of phenyl deuterium (PhD) and the byproduct magnesium deuteroxide (MgBrOD).

### Step 4: Write the Products
The products of the reaction can be summarized as follows:
- The phenyl group (Ph⁻) picks up a deuterium (D⁺) from D₂O, resulting in PhD.
- The remaining part of D₂O loses an OH group and combines with MgBr to form MgBrOD.

### Step 5: Final Product Structure
The final product is:
- PhD (deuterated phenyl compound) and MgBrOD.

### Conclusion
Thus, the final products of the reaction are PhD and MgBrOD.

### Final Answer
The product (X) in the reaction `PhMgBr + D₂O → (X), (X)` will be PhD and MgBrOD.
