Out of o-dichlorobenzene and p-dichlorobenzene, which has higher melting point and why?

Explanation

To determine which compound has a higher melting point between o-dichlorobenzene and p-dichlorobenzene, we can analyze their structures and intermolecular forces.

### Step-by-step Solution:

1. **Identify the Structures**:
- **o-Dichlorobenzene** (ortho-dichlorobenzene) has the two chlorine atoms attached to adjacent carbon atoms on the benzene ring.
- **p-Dichlorobenzene** (para-dichlorobenzene) has the two chlorine atoms attached to opposite carbon atoms on the benzene ring.
