Why do compounds having similar geometry have different magnetic moment ?

Explanation

**Step-by-Step Solution:**

1. **Understanding Magnetic Moments:**
- The magnetic moment of a compound is influenced by the number of unpaired electrons in its d-orbitals. Compounds with unpaired electrons exhibit paramagnetism, while those with all paired electrons are diamagnetic.

2. **Identifying Ligands:**
- Ligands can be classified as weak field ligands or strong field ligands. Weak field ligands (like fluorine) do not cause significant splitting of d-orbitals, leading to high spin complexes. Strong field ligands (like ammonia) cause greater splitting, resulting in low spin complexes.
