The Beilstein test for organic compounds is used to detect

Options

A. carbon
B. halogens
C. nitrogen
D. sulphur

Explanation

**Step-by-Step Text Solution:**

1. **Understanding the Beilstein Test:**
The Beilstein test is a qualitative test used to detect the presence of halogens in organic compounds.

2. **Identifying the Purpose of the Test:**
The primary purpose of the Beilstein test is to identify halogens (such as chlorine, bromine, and iodine) in a given organic sample.

3. **Procedure of the Beilstein Test:**
- A copper wire is first heated in a Bunsen burner flame until it forms copper oxide.
- The heated copper oxide is then dipped into the organic sample that is being tested.
- After dipping, the copper wire is brought back near the flame.

4. **Observation:**
- If the sample contains halogens, a green flame will be observed. This green flame indicates the formation of copper halides, confirming the presence of halogens in the sample.

5. **Exceptions:**
- It is important to note that the Beilstein test does not detect fluorides; they are an exception to this test.

6. **Conclusion:**
Therefore, the Beilstein test is specifically used for the detection of halogens in organic compounds.
