Q45.Which of the following compounds show colour due to d - d transition? (1) CuSO4 ยท 5H2O (2) K2Cr2O7 (3) K2CrO4 (4) KMnO4
What This Question Tests
This question differentiates between colour arising from d-d transitions (typical for compounds with partially filled d-orbitals) and charge transfer transitions (for compounds where d-orbitals are empty or fully filled but highly coloured).
