On dissolving in ___________ electrovalent compounds undergo dissociation. (water/benzene/chloroform)

Explanation

To solve the question "On dissolving in ___________ electrovalent compounds undergo dissociation," we need to determine which solvent among the given options (water, benzene, chloroform) allows electrovalent (ionic) compounds to dissociate.

### Step-by-Step Solution:

1. **Understand Electrovalent Compounds**:
- Electrovalent compounds, also known as ionic compounds, are formed by the electrostatic attraction between positively and negatively charged ions. For example, sodium chloride (NaCl) is an ionic compound formed from Na⁺ and Cl⁻ ions.

2. **Identify the Nature of the Solvents**:
...
