Which of the following statements correctly describes the trend in the energy required for Ligand to Metal Charge Transfer (LMCT) transitions in oxo-anions of transition metals moving down a group in the periodic table?
1
The energy required for LMCT decreases as the size of the metal cation increases.
2
The energy required for LMCT increases due to the increasing energy of LUMO on moving from 3d to 5d series.
3
The energy required for LMCT remains constant as the size of the metal cation has no effect on LUMO energy.
4
The energy required for LMCT decreases as the oxidation state of the metal cation decreases.
