Question

13. Transition metal ions form coloured compounds due to :

i) d-d transition ii) charge transfer spectrum

iii) their high oxidation states iv) vacant d-orbitals

1) all 2) i, ii, iii 3) i, ii, iv 4) i & ii​

Answer 1

Answer:

The reason why transition metal in particular are colorful is because they have unfilled or either half filled d orbitals. There is Crystal field theory which explains the splitting of the d orbital, which splits the d orbital to a higher and lower orbital. Now, the electrons of the transition metal can "jump".
