Write the IUPAC name of the following complex: \([\text{Co}(\text{NH}_3)_5(\text{CO}_3)]\text{Cl}\).
The IUPAC name of the complex \([\text{Co}(\text{NH}_3)_5(\text{CO}_3)]\text{Cl}\) is Pentaamminecarbonato cobalt(III) chloride.
Explanation:
- "Pentaammine" refers to the five ammonia (\(\text{NH}_3\)) ligands.
- "Carbonato" refers to the carbonate (\(\text{CO}_3\)) ligand.
- "Cobalt(III)" indicates that cobalt is in the +3 oxidation state.
- "Chloride" is the anion that balances the charge of the complex.
The Crystal Field Theory (CFT) of coordination compounds is based on the effect of different crystal fields (provided by the ligands taken as point charges) on the degeneracy of d-orbital energies of the central metal atom/ion. The splitting of the d-orbitals provides different electronic arrangements in strong and weak crystal fields. In tetrahedral coordination entity formation, the d-orbital splitting is smaller as compared to the octahedral entity.

On the basis of CFT, explain why [Ti(H$_2$O)$_6$]Cl$_3$ complex is coloured? What happens on heating the complex [Ti(H$_2$O)$_6$]Cl$_3$? Give reason.
