The colour of the transition metal ions ...

The colour of the transition metal ions is/are due to:

A

d - s transition

B

d - d transition

C

f - f transition

D

d - f transition

Text Solution

Verified by Experts

The correct Answer is:
B
Five degenerate d-orbitals splits up into set of two orbitals `t_(2g)` and eg. Transition of `e^-` between these d-orbitals result in d-d transition imparting colour.

Transition metals normally have unfilled 'd' orbitals which are degenerate. The colour of transition metal ions is due to absorption of light in visible region. Which of the following transition is responsible for providing the colour?

The colours of the transition metal are due to d-d excitation. The energy required for d-d electron axcitation is available in the visible range. Transition metal ions have the tendency to absorb certain rediations from the visible region and exhibit the complementary colour. The transition metal ions which have completely filled d-orbitals are colourless as the excitation of electron or electrons is not possible within d-orbitals. The transition metal ions which have completely empthy d-orbitals are also colourless. In KMnO_4 and K_2Cr_2O_7 , there are no unpaired electrons at the central atom but they are dep in colour. The colour of these compounds is due to charge transfer spectrum. for example in MnO_4 electron is momentrily transferred from O to the metal and thuys oxygen changes from O^(2-) and O^(ɵ) maganese from Mn^(7+) to Mn^(6+) . Q. Which of the following is paramagnetic as well as coloured ion?
