Explain the experimental facts that cannot be explained by the simple model of Werner's theory.

Answer:

(a) Red form

(b) Green form

Complexes with Different Arrangements of the Same Ligands Have Different Properties. The $\left[\mathrm{Co}\left(\mathrm{NH}_{3}\right)_{x} \mathrm{Cl}_{2}\right]^{+}$ ion can have two different arrangements of the ligands, which results in different colors: if the two $\mathrm{Cl}^{-}$ ligands are next to each other, the complex is red (a), but if they are opposite each other, the complex is b.
