Benzal chloride on hydrolysis gives

Options

A. Benzyl alcohol
B. Benzoic acid
C. Benzaldehyde
D. Benzo tri alcohol

Answer

To solve the question "Benzyl chloride on hydrolysis gives," we need to follow these steps:

### Step 1: Understand the Structure of Benzyl Chloride
Benzyl chloride is a compound where a benzene ring is attached to a CH2 group, which is further attached to a chlorine atom. The structure can be represented as follows:

\[ \text{C}_6\text{H}_5\text{CH}_2\text{Cl} \]

### Step 2: Hydrolysis of Benzyl Chloride
Hydrolysis involves the reaction of benzyl chloride with water, often facilitated by a base like sodium hydroxide (NaOH). The reaction can be summarized as:

\[ \text{C}_6\text{H}_5\text{CH}_2\text{Cl} + \text{NaOH} \rightarrow \text{C}_6\text{H}_5\text{CH}_2\text{OH} + \text{NaCl} \]

In this step, the chlorine atom is replaced by a hydroxyl group (OH) from sodium hydroxide, forming benzyl alcohol.

### Step 3: Further Hydrolysis
If we continue the hydrolysis process, we can add another molecule of NaOH. This will lead to the formation of benzoic acid. The reaction can be represented as:

\[ \text{C}_6\text{H}_5\text{CH}_2\text{OH} + \text{NaOH} \rightarrow \text{C}_6\text{H}_5\text{COOH} + \text{H}_2\text{O} + \text{NaCl} \]

Here, the hydroxyl group from the first hydrolysis becomes part of the carboxylic acid group (COOH), and water is released as a by-product.

### Step 4: Identify the Final Product
The final product after the complete hydrolysis of benzyl chloride is benzaldehyde, which can be represented as:

\[ \text{C}_6\text{H}_5\text{CHO} \]

### Conclusion
Thus, the hydrolysis of benzyl chloride ultimately gives benzaldehyde as the product.

### Final Answer
Benzaldehyde.
