Benzaldehyde can be prepared by the hydrolysis of

Options

A. benzal chloride
B. benzotrichloride
C. benzyl chloride
D. benzonitrile

Explanation

To prepare Benzaldehyde through hydrolysis, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Starting Material**:
Benzaldehyde (C₇H₆O) can be prepared from Benzyl Chloride (C₇H₇Cl) through hydrolysis. Benzyl Chloride consists of a benzene ring attached to a CH₂Cl group.

2. **Hydrolysis Reaction**:
When Benzyl Chloride undergoes hydrolysis, it reacts with water (H₂O) in the presence of a nucleophile, which is typically hydroxide ion (OH⁻) or water itself. The reaction can be represented as:
\[ C₇H₇Cl + H₂O \rightarrow C₇H₇OH + HCl \]
This reaction leads to the formation of Benzyl Alcohol (C₇H₈O) and Hydrochloric Acid (HCl).

3. **Conversion of Benzyl Alcohol to Benzaldehyde**:
Benzyl Alcohol can be oxidized to Benzaldehyde. This can be achieved using mild oxidizing agents such as PCC (Pyridinium chlorochromate) or even through air oxidation. The reaction is as follows:
\[ C₇H₈O + [O] \rightarrow C₇H₆O + H₂O \]
Here, the hydroxyl group (–OH) in Benzyl Alcohol is converted to the carbonyl group (–CHO) in Benzaldehyde.

4. **Final Product**:
The final product of this reaction sequence is Benzaldehyde (C₇H₆O).

### Conclusion:
Thus, Benzaldehyde can be prepared by the hydrolysis of Benzyl Chloride.
