Haloarenes are less reactive than haloalkanes and haloalkenes. Explain.

Explanation

### Step-by-Step Solution

1. **Understanding the Structures**:
- Begin by recognizing the basic structures of haloarenes and haloalkanes. Haloarenes contain a halogen atom (X) attached to a benzene ring, while haloalkanes consist of a halogen atom attached to an aliphatic carbon chain.

2. **Resonance in Haloarenes**:
- In haloarenes, the presence of the halogen atom allows for resonance. The lone pairs of electrons on the halogen can interact with the π-electrons of the benzene ring. This interaction leads to the delocalization of electrons, creating multiple resonance structures.
