Vedclass · Answer

(A) Transition metal compounds exhibit colour due to $d-d$ transitions,which require the presence of unpaired electrons. Substances with unpaired electrons are paramagnetic. Therefore,coloured compounds are generally paramagnetic. Conversely,colourless compounds lack unpaired electrons,making them diamagnetic. Thus,the statement that 'Colourless compounds of transition elements are paramagnetic' is incorrect.
