In +2 oxidation state, which of the following lanthanoids act as reducing agents?
- A \(\mathrm{Ce}, \mathrm{Pr}\)
- B \(\mathrm{Eu}, \mathrm{Gd}\)
- C \(\mathrm{Eu}, \mathrm{Yb}\)
- D \(\mathrm{Lu}, \mathrm{Er}\)
Answer & Solution
Correct Answer
(C) \(\mathrm{Eu}, \mathrm{Yb}\)
Step-by-step Solution
Detailed explanation
Both \(\mathrm{Eu}^{+2}\) and \(\mathrm{Yb}^{+2}\) tends to acquire common oxidation state of +3 by loosing 1 electron and becomes highly stable.
