Which one of the following will give a primary amine of hrdrolysis?

Options

A. nitroparaffins
B. Alkyl cyanide
C. amide
D. Alkyl isocyanide

Answer

To determine which compound will give a primary amine upon hydrolysis, we need to analyze the options provided: nitro paraffins, alkyl cyanide, amide, and alkyl isocyanide.

### Step-by-Step Solution:

1. **Understanding Hydrolysis**:
Hydrolysis is a chemical reaction involving the breaking of a bond in a molecule using water. In the context of amines, we are interested in how different compounds can yield primary amines when they undergo hydrolysis.

2. **Analyzing Each Option**:
- **Nitro Parafins**: These compounds contain a nitro group (-NO2) attached to a paraffin chain. Hydrolysis does not convert nitro groups into amines directly.
- **Alkyl Cyanide**: Alkyl cyanides (R-CN) can be hydrolyzed to yield carboxylic acids and ammonia, but they do not yield primary amines directly.
- **Amide**: Amides (R-CO-NH2) can be hydrolyzed to yield carboxylic acids and amines. However, the amine produced from a simple amide is typically a primary amine only if the amide itself is a primary amide.
- **Alkyl Isocyanide**: Alkyl isocyanides (R-N≡C) undergo hydrolysis to yield primary amines and formic acid (HCOOH). The reaction can be represented as:
\[ R-N \equiv C + H_2O \rightarrow R-NH_2 + HCOOH \]
Here, R-NH2 is a primary amine.

3. **Conclusion**:
Based on the analysis, the compound that gives a primary amine upon hydrolysis is **alkyl isocyanide**. Therefore, the correct answer is option D: **alkyl isocyanide**.
