Step-by-Step Verified Solution
The +3 oxidation state of lanthanide is most stable and therefore lanthanide in +4 oxidation state has strong tendence to gain e– and converted into +3 and therefore act as strong oxidizing agent. eg Ce+4
And therefore CeO2 is used to oxidized alcohol aldehyde and ketones.
Lanthanide in +2 oxidation state has strong tendency to loss e– and converted into +3 oxidation state therefore act as strong reducing agent.
EuSO4 act as a strong reducing agent.
And therefore CeO2 is used to oxidized alcohol aldehyde and ketones.
Lanthanide in +2 oxidation state has strong tendency to loss e– and converted into +3 oxidation state therefore act as strong reducing agent.
EuSO4 act as a strong reducing agent.
