How many of the following are coloured, but not because of d–d transitions? KMnO₄, K₂CrO₄, HgI₂, [Ti(H₂O)₆]³⁺, CdS, [Co(NH₃)₆]³⁺, I₂ vapour, [Zn(H₂O)₆]²⁺, NaCl
Answer:
5
Solution:
KMnO₄, K₂CrO₄, HgI₂ and CdS are coloured by charge-transfer or band-gap absorption, and I₂ by a molecular π*→σ* transition. [Ti(H₂O)₆]³⁺ and [Co(NH₃)₆]³⁺ are d–d coloured. [Zn(H₂O)₆]²⁺ (d¹⁰) and NaCl are colourless. Count = 5.
