प्रश्न
Answer the following question.
Draw a qualitatively energy-level diagram showing d-orbital splitting in the octahedral environment. Predict the number of unpaired electrons in the complex [Fe(CN)6]4-. Is the complex diamagnetic or paramagnetic? Is it coloured? Explain.
उत्तर
i. Diagram:
ii. There are no unpaired electrons in t2g orbital; hence, the complex is diamagnetic.
iii. In the complex, d-d transitions do not occur and hence, it is colourless.
