A d-block element forms octahedral complex but its magnetic moment remains same either in strong field or in weak field ligand. Which of the following is/are correct?

Answer»

Element ALWAYS forms colourless compound
Number of electron in `t_(2g)` ORBITALS are higher than in `e_(g)` orbitals
It can have either `d^(3) or d^(8)` configuration
It can have either `d^(7) or d^(8)` configuration

Solution :Irrespective nature of ligand field, magnetic moment of OCTAHEDRAL complexes having metal ions in `d^(1),d^(2),d^(3),d^(8),d^(9)` configuration, remains same.
Element may or may not form colourless complex.
