Hydrolysis of phenyl isocyanide forms :

Options

A. benzoic acid
B. formic acid
C. acetanilide
D. acetic acid

Answer

To solve the question regarding the hydrolysis of phenyl isocyanide, we will follow these steps:

### Step-by-Step Solution:

1. **Identify the Structure of Phenyl Isocyanide**:
- Phenyl isocyanide has the structure C6H5-NC. It consists of a phenyl group (C6H5) attached to an isocyanide group (NC).

2. **Understanding Hydrolysis**:
- Hydrolysis refers to the reaction of a compound with water. In this case, phenyl isocyanide will react with water (H2O) in the presence of an acid (H+).

3. **Formation of Intermediate Compound**:
- When phenyl isocyanide undergoes hydrolysis, it first forms an intermediate compound known as N-phenyl formamide. The reaction can be represented as:
\[ \text{C6H5-NC} + \text{H2O} \xrightarrow{\text{H}^+} \text{C6H5-NH-C(=O)H} \]
- This intermediate is N-phenyl formamide (C6H5-NH-CHO).

4. **Further Hydrolysis of the Intermediate**:
- The intermediate N-phenyl formamide can undergo further hydrolysis. The carbonyl carbon (C=O) of the formamide can react with water to form an acid and an amine:
\[ \text{C6H5-NH-C(=O)H} + \text{H2O} \xrightarrow{\text{H}^+} \text{C6H5-NH2} + \text{HCOOH} \]
- This results in the formation of aniline (C6H5-NH2) and formic acid (HCOOH).

5. **Conclusion**:
- The products of the hydrolysis of phenyl isocyanide are aniline and formic acid. Since the question asks for the products and one of the options is formic acid, the correct answer is:
- **Formic acid** (Option 2).

### Final Answer:
The hydrolysis of phenyl isocyanide forms **formic acid**.
