Given below are two statements:
Statement I: $\mathrm{CeO}_2$ can be used for oxidation of aldehydes and ketones.
Statement 11 : Aqueous solution of $\mathrm{EuSO}_4$ is a strong reducing agent.
In the light of the above statements, choose the correct answer from the options given below:
Select the correct option:
A
Statement I is false but statement II is true
B
Statement I is true but statement II is false
C
Both statement I and statement II are true
D
Both statement I and statement II are false
✓ Correct! Well done.
✗ Incorrect. Try again or view the solution.
Solution
The +3 oxidation state of lanthanide is most stable and therefore lanthanide in +4 oxidation state has strong tendence to gain $\mathrm{e}^{-}$and converted into +3 and therefore act as strong oxidizing agent.
eg. $\mathrm{Ce}^{+4}$
And there fore $\mathrm{CeO}_2$ is used to oxidized alcohol aldehyde and ketones.
Lanthanide in +2 oxidation state has strong tendency to loss $\mathrm{e}^{-}$and converted into +3 oxidation state therefore act as strong reducing agent.
$\therefore \mathrm{EuSO}_4$ act as strong reducing agent.
