The functional group in secondary amines is known as_____________.

Options

A. amino group
B. imino group
C. tertiary nitrogen
D. azo group

Answer

To answer the question about the functional group in secondary amines, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Secondary Amines**:
- Secondary amines are defined as amines where the nitrogen atom is bonded to two carbon atoms and one hydrogen atom. This means that the nitrogen is connected to two alkyl groups (R and R') and one hydrogen atom.

2. **Identifying the Functional Group**:
- The functional group in amines is characterized by the presence of a nitrogen atom (N). In the case of secondary amines, the specific arrangement is that the nitrogen is bonded to two carbon atoms and one hydrogen atom.

3. **Naming the Functional Group**:
- The specific functional group for secondary amines is referred to as the "imino group." The imino group is represented as -NH- (where the nitrogen is bonded to carbon atoms).

4. **Conclusion**:
- Therefore, the functional group in secondary amines is known as the "imino group."

### Final Answer:
The functional group in secondary amines is known as **imino**.
