Question

tell ans...........
Assign reasons for each of the following:

1) Transition metals generally form coloured compounds. (ii) Manganese exhibits the highest oxidation state of +7 among the

transition elements.​

Answer 1

Answer:

Colour of compounds of transition elements depends upon the unpaired electrons present in d orbitals of transition elements. If d orbitals are completely vacant as in Sc

3+

,Ti

4+

or completely filled as in Cu

+

,Zn

2+

, the compounds will be colourless. But if any unpaired electron is present in d-orbitals, the compound will be coloured due to d→d transition.
