A metal ion `M^(n+)` having `d^(4)` valence electronic configuration combines with three didentate ligands to form a complex compound. Assuming `Delta_(@)gt P` :
(i) Draw the diagram showing d-orbital splitting during this comples formation.
(ii) What type of hybridisation will `M^(n+)` have?
(iii) Name the type of isomerism exhibited by this complex.
(iv) Write the electronic configuration of metal `M^(n+)`

Explanation

To solve the given question step by step, we will address each part of the question systematically.

### Step 1: Draw the diagram showing d-orbital splitting during complex formation.

**Solution:**
In an octahedral complex, the d-orbitals split into two sets due to the presence of ligands. The lower energy set is called T2g (comprising dxy, dyz, and dxz orbitals), and the higher energy set is called Eg (comprising dx2-y2 and dz2 orbitals).

1. Start with the five degenerate d-orbitals: dxy, dyz, dxz, dx2-y2, and dz2.
