Name a compound which does not contain halogen but gives positive Beilestein test.

Answer

### Step-by-Step Solution:

1. **Understanding the Beilstein Test**: The Beilstein test is a qualitative test used to detect the presence of halogens in organic compounds. It involves heating a copper wire in a flame and then dipping it into the organic compound. If halogens are present, a green flame will be observed due to the formation of copper halides.

2. **Identifying a Compound Without Halogens**: The question asks for a compound that does not contain halogens but still gives a positive Beilstein test. This means we need to find a compound that can react to produce a halogen-containing product.

3. **Considering Urea**: Urea is a compound with the formula NH₂CONH₂. It does not contain any halogen atoms. However, it can react with certain reagents to produce halogenated products.

4. **Reaction of Urea**: When urea is heated with copper (II) oxide (CuO) in the presence of a halogen source, it can produce phosgene (COCl₂), which contains chlorine. This reaction is what gives the positive Beilstein test.

5. **Conclusion**: Therefore, the compound that does not contain halogen but gives a positive Beilstein test is **Urea (NH₂CONH₂)**.

### Final Answer:
The compound that does not contain halogen but gives a positive Beilstein test is **Urea (NH₂CONH₂)**.
