Out of o- and p-dibromobenzene which one has higher melting point and why?

Explanation

To determine which compound, o-dibromobenzene or p-dibromobenzene, has a higher melting point, we can analyze their structures and the implications of symmetry on their physical properties.

### Step-by-Step Solution:

1. **Identify the Structures**:
- **Ortho-Dibromobenzene (o-dibromobenzene)**: In this compound, the two bromine atoms are attached to adjacent carbon atoms on the benzene ring. This results in a structure where the bromine atoms are close to each other.
- **Para-Dibromobenzene (p-dibromobenzene)**: In this compound, the two bromine atoms are attached to carbon atoms that are opposite each other on the benzene ring, resulting in a more symmetrical structure.
