Which of the following statements related to crystal field splitting in octahedral coordination entities is incorrect?

Answer»

The `d_(x)^(2)-d_(y)^(2) and d_(Z)^(2)` ORBITALS has more energy is compared to `d_(xy),d_(yz) and d_(xy)` orbitals.
Crystal field splitting energy `(Delta_(a))` depends directly on the charge of the METAL ion and on the field produced by the ligand.
In the presence of `Br^(-)` as a ligand the distribution of electrons for `d^(4)` configuration will be `t_(2)^(3)g,e_(g)^(1)`,
In the presence of `CN^(-)` as a ligand `Delta_(@) LT P`.

Solution :`CN^(-)` is a strong field ligand and form low spin complexes thus `Delta_(a) GT P`.
