Question: which one of the following does not show colour due to charge transfer transition?
Answer: The Brainliest Answer! For example, the orange colour of TiBr4, yellow colour of CrO42– , orange colour of Cr2O2–7, intense red colour of [Fe(SCN)4] and deep purple of MnO4 are not due to d—d transitions. In the case of MnO4 ion, the color is due to charge transfer and not due to d-d transitions.
