Interpretation Introduction

Interpretation:

The crystal field splitting energy $\Delta$ in kJ/mol for the complex ${\left[{\text{Ti(NCS)}}_{\text{6}}\right]}^{\text{3-}}$ needs to be determined. Whether NCS- is a stronger or weakerligand and the color of complex needs to be determined.

Concept introduction:

The d orbitals in an octahedral complex divides into two sets of different energies. The separation of energy is known as crystal filed splitting energy $\Delta$. This is because, the d orbitals splits when it starts bonding with other ligands. The bonding is due to difference in symmetries of d orbitals and the inductive effect of ligands on electrons.
