Chapter 23, Problem 101IE

Interpretation Introduction

Interpretation: The expected wavelength of the absorption corresponding to promotion of an electron from the lower energy to the higher energy d orbital for the given complex is to be determined and if the given complex absorbs in the visible range is to be stated.

Concept introduction: Absorption of light depends upon the energy gap between $t_{2}g$ and $e_g$ orbitals. If the gap is small than the absorbed wavelength is large and if the gap is large than the absorb wavelength is small.

To determine: The expected wavelength of the absorption corresponding to promotion of an electron from the lower energy to the higher energy d orbital for the given complex and if the given complex absorbs in the visible range.
