Carbylamine test is used in the detection of

Options

A. Aliphatic `2^(@)` amine
B. Aromatic `1^(@)` amine
C. Aliphatic `1^(@)` amine
D. Both aliphatic and aromatic `1^(@)` amines

Answer

### Step-by-Step Solution:

1. **Understanding the Carbylamine Test**:
The Carbylamine test is a qualitative test used to detect primary amines. It is particularly useful for identifying both aliphatic and aromatic primary amines.

2. **Chemical Reaction Involved**:
The test involves the reaction of a primary amine (RNH₂) with chloroform (CHCl₃) in the presence of a strong base, typically potassium hydroxide (KOH). The reaction can be summarized as follows:
\[ \text{RNH}_2 + \text{CHCl}_3 + 3\text{KOH} \rightarrow \text{RNC} + 3\text{KCl} + 3\text{H}_2\text{O} \]
Here, RNC represents the isocyanide (or carbylamine) produced.

3. **Observation of the Test**:
The key observation in the Carbylamine test is the production of an unpleasant smell due to the formation of isocyanides. This distinct odor is a hallmark of the presence of primary amines.

4. **Conclusion**:
The Carbylamine test is specifically used for the detection of primary amines, which can be either aliphatic or aromatic. Therefore, the correct answer to the question is that the Carbylamine test detects both aliphatic and aromatic primary amines.

### Final Answer:
The Carbylamine test is used in the detection of primary amines, both aliphatic and aromatic.
