The purification of a organic compound is varified with

Options

A. Melting point
B. Molecular weight
C. Density
D. Solubility in water

Explanation

**Step-by-Step Solution:**

1. **Understanding Purification of Organic Compounds**:
- Purification is a crucial process in organic chemistry that aims to isolate a compound in its pure form. It is essential to verify the purity of the compound after purification.

2. **Criteria for Purity**:
- The purity of an organic compound can be assessed using various physical properties. The most common criteria include:
- Melting Point (for solids)
- Boiling Point (for liquids)
- Density
- Solubility in water

3. **Melting Point as a Purity Indicator**:
- The melting point is a specific temperature at which a solid becomes a liquid. Pure substances have a sharp melting point, while impure substances exhibit a range of melting points.
- Therefore, measuring the melting point of a solid organic compound can effectively indicate its purity. A sharp melting point suggests that the compound is pure, while a depressed or broadened melting point indicates the presence of impurities.

4. **Conclusion**:
- Among the options provided, the most reliable method for verifying the purity of an organic compound is by determining its melting point.

**Final Answer**: The purification of an organic compound is verified with the **melting point**.
