Soda lime test is used to detect one of the following element of organic compound

Options

A. C
B. H
C. N
D. S

Answer

**Step-by-Step Solution:**

1. **Understanding Soda Lime**: Soda lime is a mixture of sodium hydroxide (NaOH) and calcium oxide (CaO). It is commonly used in organic chemistry for various tests.

2. **Purpose of the Soda Lime Test**: The soda lime test is primarily used to detect the presence of certain elements in organic compounds. It is particularly known for its ability to react with specific functional groups.

3. **Analyzing the Options**:
- **Option 1: Carbon**: While carbon is a fundamental element in organic compounds, the soda lime test does not specifically detect carbon.
- **Option 2: Hydrogen**: Similar to carbon, hydrogen is also present in organic compounds but is not specifically detected by the soda lime test.
- **Option 3: Nitrogen**: The soda lime test can detect nitrogen-containing compounds. When these compounds are heated with soda lime, they can produce ammonia (NH3), indicating the presence of nitrogen.
- **Option 4: Sulphur**: The soda lime test is not used to detect sulphur in organic compounds.

4. **Conclusion**: Based on the analysis, the soda lime test is specifically used to detect the presence of nitrogen in organic compounds. Therefore, the correct answer is **Option 3: Nitrogen**.
