MHT CET 2026 Chemistry question

Identify the factor responsible for colour of transition metal compounds

(A)d-d transitionsCorrect
(B)s-p mixing
(C)Ionisation
(D)Shielding effect

Answer: (A)

Solution

In transition metal ions the d orbitals are split in energy by the surrounding ligands/water molecules. A d electron absorbs a photon of visible light and jumps from a lower to a higher d level (d-d transition); the complementary colour
