Options

A. `1^(@)` Amine `
B. `2^(@)` Amine
C. `3^(@)` Amine
D. Quaternary salt

Answer

To determine the classification of tertiary butyl amine, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of Tertiary Butyl Amine**:
- Tertiary butyl amine is derived from butane and has the formula (CH₃)₃CNH₂. It consists of a butyl group attached to a nitrogen atom.

2. **Identify the Degree of Amine**:
- Amines are classified based on the number of carbon-containing groups (R groups) attached to the nitrogen atom (N).
- **Primary amine (1°)**: Has one R group (RNH₂).
- **Secondary amine (2°)**: Has two R groups (R₂NH).
- **Tertiary amine (3°)**: Has three R groups (R₃N).
- **Quaternary ammonium salt**: Has four R groups (R₄N⁺X⁻).

3. **Analyze Tertiary Butyl Amine**:
- In the case of tertiary butyl amine, the nitrogen atom is attached to three carbon groups (the three methyl groups from the butyl group).
- Therefore, it fits the definition of a tertiary amine (3°).

4. **Conclusion**:
- Based on the analysis, tertiary butyl amine is classified as a tertiary amine.

### Final Answer:
Tertiary butyl amine is a tertiary amine (3° amine).
