In an octahedral crystal field, d - orbitals split into ….. Orbitals collectively called ….. And ….. Orbitals collectively called …..

Explanation

To answer the question regarding the splitting of d-orbitals in an octahedral crystal field, we can break down the solution into clear steps:

### Step-by-Step Solution:

1. **Understanding the Octahedral Crystal Field**:
- In an octahedral crystal field, the arrangement of ligands around the central metal ion is octahedral, meaning there are six ligands positioned at the vertices of an octahedron.

2. **Splitting of d-Orbitals**:
