Chemistry The d and f-Block Elements JEE Main 2024

The orange colour of K₂Cr₂O₇ and purple colour of KMnO₄ is due to

(A)d → d transitions in K₂Cr₂O₇ and charge transfer transitions in KMnO₄
(B)d → d transitions in KMnO₄ and charge transfer transitions in K₂Cr₂O₇
(C)Charge transfer transition in bothCorrect
(D)d → d transitions in both

Answer: (C)

Solution

Cr in K₂Cr₂O₇ (+6) and Mn in KMnO₄ (+7) are d⁰ ions, so no d–d transitions are
