Explanation

To solve the given question step by step, we will break down each part of the question and provide a detailed explanation.

### (a) Describe heterolytic (polar) bond cleavage of:
1. **AgI**
- In silver iodide (AgI), the bond between silver (Ag) and iodine (I) is polar due to the difference in electronegativity. Iodine is more electronegative than silver, which means it attracts the shared electron pair more strongly.
- During heterolytic cleavage, the bond breaks in such a way that the electron pair is transferred to the more electronegative atom (I). This results in the formation of a cation (Ag⁺) and an anion (I⁻).
- **Products:** Ag⁺ + I⁻
