Correct answer
DBoth Statement I and Statement II are true
Step-by-step explanation
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.
