Why covalent molecules show isomerism but ionic compound do not ?

Explanation

### Step-by-Step Solution:

1. **Understanding Covalent Bonds**:
- Covalent bonds are formed when two atoms share electrons. This sharing occurs through the overlapping of atomic orbitals.

2. **Directionality of Covalent Bonds**:
- The overlapping of orbitals in covalent bonds is directional. This means that the orientation of the bonds is important, and the specific arrangement of atoms can lead to different spatial configurations, known as isomers.
