Haloalkanes react with KCN to form alkyl cyanides as main product while AgCN forms isocyanides as the chief product. Explain.

Explanation

To explain why haloalkanes react with KCN to form alkyl cyanides as the main product while AgCN forms isocyanides as the chief product, we can break down the process into clear steps:

### Step-by-Step Solution:

1. **Understanding the Reactants**:
- Haloalkanes are organic compounds containing a halogen atom (like Cl, Br, or I) attached to an alkane carbon chain.
- KCN (potassium cyanide) and AgCN (silver cyanide) are both cyanide sources, but they behave differently in reactions due to their structural characteristics.
