Question:
Which of the following statements related to lanthanoids is incorrect?
Which of the following statements related to lanthanoids is incorrect?
Show Hint
Lanthanoid ion colors arise from f-f transitions within partially filled f-orbitals.
Updated On: Dec 26, 2024
- Lanthanoids are silvery white metals.
- Samarium shows +2 oxidation state.
- Ce⁴⁺ solutions are oxidizing agents.
- Colour of lanthanoids is due to d-d transitions.
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
The colour of lanthanoid ions in solution is due to f-f transitions, not d-d transitions. Lanthanoids have partially filled f-orbitals, and their electronic transitions occur within the f-orbital.
