A. Position Isomers
B. chain isomers
C. functional isomers
D. Geometrical isomers

Answer

To classify 1°, 2°, and 3° amines that have the same number of carbon atoms, we can follow these steps:

### Step 1: Understand the Types of Isomerism
Isomerism refers to compounds that have the same molecular formula but differ in structure or arrangement. The main types of isomerism relevant to amines include:
- **Position Isomerism**: Different positions of the functional group (amino group).
- **Chain Isomerism**: Different carbon chain arrangements.
- **Functional Isomerism**: Different functional groups or types of compounds.
- **Geometrical Isomerism**: Different spatial arrangements.

### Step 2: Analyze the Given Amines
1. **Primary Amine (1°)**: Has one alkyl group attached to the nitrogen (e.g., CH3CH2CH2NH2).
2. **Secondary Amine (2°)**: Has two alkyl groups attached to the nitrogen (e.g., CH3CH2NHCH3).
3. **Tertiary Amine (3°)**: Has three alkyl groups attached to the nitrogen (e.g., CH3N(CH3)2).

### Step 3: Evaluate Each Type of Isomerism
- **Position Isomerism**: This involves the same carbon skeleton but different positions of the amino group. This does not apply since we are comparing different degrees of amines, not different positions of the same amine.

- **Chain Isomerism**: This involves different carbon chain arrangements. This is not applicable here as we are comparing amines with the same number of carbons but different degrees.

- **Functional Isomerism**: Primary, secondary, and tertiary amines can have the same molecular formula (e.g., C3H9N) but differ in the type of amine they represent. This is the correct classification for our case.

- **Geometrical Isomerism**: This does not apply to amines as they do not have the necessary conditions for geometrical isomerism (like double bonds or rings).

### Conclusion
The correct classification of 1°, 2°, and 3° amines with the same number of carbon atoms is **Functional Isomerism**.

### Final Answer
**Functional Isomerism**
