Current Question (ID: 18753)

Question:

$\text{The crystal field splitting energy is:}$

Options:

1. $\text{The heat of formation between the two levels (} e_g \text{ and } t_{2g} \text{)}$
2. $\text{The combined pairing energy of the two levels (} e_g \text{ and } t_{2g} \text{)}$
3. $\text{The combined energy of the three levels in octahedral}$
4. $\text{The combined energy of the two levels (} e_g \text{ and } t_{2g} \text{)}$

Solution:

$\text{HINT: CFSE is the energy difference between } e_g \text{ and } t_{2g}$ $\text{The degenerated orbitals (in a spherical field environment) split into two levels i.e., } e_g \text{ and } t_{2g} \text{ in the presence of ligands.}$ $\text{The splitting of the degenerate levels due to the presence of ligands is called crystal-field splitting while the energy difference}$ $\text{between the two levels (} e_g \text{ and } t_{2g} \text{) is called the crystal-field splitting energy.}$ $\text{It is denoted by } \Delta_o.$
