Which of the following statements about sodium chloride is incorrect?

Options

A. It has high melting point
B. It conducts electricity in molten state
C. It is soluble in water.
D. It is soluble in ether.

Explanation

To determine which statement about sodium chloride (NaCl) is incorrect, let's analyze each option step by step.

**Step 1: Analyze the first statement - "Sodium chloride has a high melting point."**
- Sodium chloride is an ionic compound formed from sodium ions (Na⁺) and chloride ions (Cl⁻). Ionic compounds typically have strong electrostatic forces between the oppositely charged ions, which results in high melting points. Therefore, this statement is **correct**.

**Step 2: Analyze the second statement - "Sodium chloride conducts electricity in molten state."**
- When sodium chloride is melted, the ionic bonds break, allowing the ions to move freely. This movement of ions enables the conduction of electricity. Thus, this statement is also **correct**.

**Step 3: Analyze the third statement - "Sodium chloride is soluble in water."**
- Sodium chloride is soluble in water because both NaCl and water (H₂O) are polar substances. The polar water molecules can surround the Na⁺ and Cl⁻ ions, effectively pulling them apart and dissolving the salt. Therefore, this statement is **correct**.

**Step 4: Analyze the fourth statement - "Sodium chloride is soluble in ether."**
- Ether is a non-polar solvent, and ionic compounds like sodium chloride do not dissolve well in non-polar solvents. Since sodium chloride is ionic and ether is non-polar, this statement is **incorrect**.

**Conclusion:**
The incorrect statement about sodium chloride is that it is soluble in ether.
