Choose incorrect statement.

AHalogens are coloured due to HOMO-LUMO transition
BDuring charge transfer, oxidation state of atoms changes
CHigher the polarisation, more is colour intensity
DComplex compound having no unpaired electron can not undergo d-d transition and therefore it is colourless
Correct Answer

Solution

Option D is incorrect as the colour of complex compounds does not depends on the number of unpaired electron, thus they can be colourless depending on the ions present in the complex.
