Give reasons for the following :
(i) `MgCl_(2)` is more covalent than NaCl (ii) CuCl is more covalent than NaCl.

Explanation

To solve the question, we need to analyze the covalent character of the compounds \( MgCl_2 \), \( NaCl \), and \( CuCl \). Here’s a step-by-step solution:

### Step 1: Understand the Ionic and Covalent Character
Ionic compounds can exhibit covalent character based on the charge and size of their ions. The greater the charge on the cation, the more it can polarize the anion, leading to a greater covalent character.

### Step 2: Analyze \( MgCl_2 \) vs \( NaCl \)
1. **Cations**:
- \( Mg^{2+} \) (from \( MgCl_2 \)) has a charge of +2.
