Problem

The value of CFSE (

\Delta_0

) for complexes given below follow the order : -

[\text{Co}(\text{NH}_3)_6]^{3+}

[\text{Rh}(\text{NH}_3)_6]^{3+}

[\text{Ir}(\text{NH}_3)_6]^{3+}

\text{I} < \text{II} < \text{III}

\text{I} > \text{II} > \text{III}

\text{I} < \text{II} > \text{III}

\text{I} = \text{II} = \text{III}
