Which of the following substances when dissolved in water will give a solution that does not conduct electricity

Options

A. Hydrogen chloride
B. potassium hydroxide
C. sodium acetate
D. Urea

Explanation

To determine which substance, when dissolved in water, will give a solution that does not conduct electricity, we need to consider the nature of the substances and how they behave in water.

### Step-by-Step Solution:

1. **Understanding Conductivity in Solutions**:
- Electrical conductivity in solutions is primarily due to the presence of ions. When a substance dissolves in water, it may dissociate into ions, which can carry electric current.

2. **Identifying the Substances**:
- List the substances provided in the question. Common examples might include ionic compounds (like NaCl), covalent compounds (like sugar), and molecular compounds.

3. **Analyzing Each Substance**:
- **Ionic Compounds**: These typically dissociate into ions when dissolved in water. For example, NaCl dissociates into Na⁺ and Cl⁻ ions, which can conduct electricity.
- **Covalent Compounds**: Many covalent compounds do not dissociate into ions in water. For example, sugar (C₁₂H₂₂O₁₁) dissolves in water but does not produce ions, hence it does not conduct electricity.
- **Molecular Compounds**: Some molecular compounds may ionize in water, while others do not.

4. **Conclusion**:
- Based on the analysis, the substance that does not produce ions when dissolved in water will not conduct electricity. For example, if sugar is one of the options, it would be the correct answer.

### Final Answer:
The substance that, when dissolved in water, will give a solution that does not conduct electricity is a covalent compound like sugar.
