Question

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?

Options

A.Element always forms colourless compound.
B.Number of electrons in t2g orbitals are higher than in eg orbitals.
C.It can have either d3 or d8 configuration.
D.It can have either d7 or d8 configuration.

Solution

Sol. (A) element form coloured compound as it contains unpaired electron.
