(i)The energy of excitation corresponds to the frequencey of light absorbed.
(ii) This frequency generally lines in the visible region.
(iii) The colour observed corresponds to the compementary colour of the light absorbed.
(iv) The frequencey of the light absorbed is determined by the nature of the ligand.
Which one of the above mentioned statements are correct?

A

I,II and Iv

B

I,II and III

C

I,II,III,and Iv

D

II and iv

Text Solution

Verified by Experts

The correct Answer is:
D
When an electron from a lower energy d-orbital is excitated to a higher energy d-orbital, the energy of excitation corresponds to the frequancy of light absorbed. This frequency generally lines in the visible region. The coloue observed corresponds to the complementary colour of the light absorbed. The frequency of light absorbed is determined by the nature of the ligand.
