Which among the following gives`1^(@) amine` on reduction?

Options

A. `CH_(3)-CH_(2)NO_(2)`
B. `CH_(3)CH_(2)-O-N=O`
C. `C_(6)H_(5)-N=NC_(6)H_(5)`
D. `CH_(3)CH_(2)NC`

Answer

To determine which compound gives a 1° amine upon reduction, we will analyze the options provided.

### Step-by-Step Solution:

1. **Identify the Compounds**:
- We need to look at the given options and identify the functional groups present in each compound. Common functional groups that can be reduced to amines include nitro groups, nitriles, and isocyanides.

2. **Reduction of Nitro Compounds**:
- If one of the options is a nitro compound (R-NO2), it can be reduced to a primary amine (R-NH2) using reducing agents like zinc with ammonium chloride or hydrogen in the presence of a catalyst.
- For example, if we have a nitro compound, upon reduction, it will yield a 1° amine.

3. **Consider Other Functional Groups**:
- If there are options with carbonyl groups (like aldehydes or ketones), they typically reduce to alcohols rather than amines.
- Nitriles (R-CN) can be reduced to 1° amines, but they usually yield 1° amines only when they are treated with specific reagents.

4. **Examine Isocyanides**:
- Isocyanides (R-NC) on reduction typically yield secondary amines (R-NH-R') rather than primary amines. Therefore, if an option is isocyanide, it will not be the correct answer.

5. **Conclusion**:
- After analyzing the options, if the only compound that can be reduced to a 1° amine is the nitro compound, then that is the correct answer.

### Final Answer:
The correct option that gives a 1° amine upon reduction is the **nitro compound**.
