Isn't Mn2+ also colourless?
Q.13. Which of the following is not coloured?
(1)
(2)
(3)
(4)
Sol. Answer (3)
does not show any colour because no any transition is possible there due to configuration.
Dear student,
Mn2+ is having five unpaired electron in d orbital and hence can undergo d-d transition . So it may coloured .
But Zn2+ is having ten electron in d orbital and hence completely filled d orbital . It cannot undergo d-d transition and hence is colourless.
