Which of the following is non-electrolyte ?

Options

A. NaCl
B. `C_(12)H_(22)O_(11)`
C. `CaCl_(2)`
D. `CH_(3)COOH`

Answer

To determine which of the following is a non-electrolyte, we need to understand what non-electrolytes are and how they differ from electrolytes.

### Step-by-Step Solution:

1. **Definition of Non-Electrolytes**: Non-electrolytes are substances that do not ionize or dissociate into ions when dissolved in water. They are typically covalent compounds and are poor conductors of electricity.

2. **Identify the Options**: We need to look at the given options (not provided in the question, but let's assume common examples like NaCl, C12H22O11, CaCl2, and acetic acid).

3. **Analyze Each Option**:
- **NaCl (Sodium Chloride)**: This is an ionic compound that dissociates into Na⁺ and Cl⁻ ions in water. Therefore, it is an electrolyte.
- **C12H22O11 (Sucrose)**: This is a covalent compound that does not dissociate into ions when dissolved in water. It is a non-electrolyte.
- **CaCl2 (Calcium Chloride)**: This ionic compound dissociates into Ca²⁺ and 2 Cl⁻ ions in water, making it an electrolyte.
- **Acetic Acid (CH3COOH)**: This weak acid partially dissociates into CH3COO⁻ and H⁺ ions in water, thus it is also considered an electrolyte.

4. **Conclusion**: Among the options analyzed, C12H22O11 (sucrose) is the only compound that does not dissociate into ions and is therefore classified as a non-electrolyte.

5. **Final Answer**: The correct answer is C12H22O11 (option 2).
