The correct Answer is:
### 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 is particularly used for identifying chlorine, bromine, and iodine. 2. **Procedure of the Beilstein Test**: - An organic compound suspected of containing halogens is heated in the presence of a copper wire or a copper salt. - If halogens are present in the organic compound, they will react with the copper to form cupric halides. 3. **Observation**: - Upon heating, a green or bluish flame is produced. This color indicates the presence of halogens, specifically due to the formation of cupric halides. 4. **Conclusion**: - Since the Beilstein test is specifically used to detect halogens, and among the options provided (N2, Cl, Na, CO2), chlorine (Cl) is the only halogen. 5. **Final Answer**: - Therefore, the Beilstein test is used for detecting the presence of chlorine (Cl).
