Given below are two statements :
Statement I : CeO2 can be used for oxidation of aldehydes and ketones.
Statement II : Aqueous solution of EuSO4 is a strong reducing agent.
In the light of the above statements, choose the correct answer from the options given below :
Statement I : CeO2 can be used for oxidation of aldehydes and ketones.
Statement II : Aqueous solution of EuSO4 is a strong reducing agent.
In the light of the above statements, choose the correct answer from the options given below :
Statement I is true but Statement II is false.
Statement I is false but Statement II is true
Both Statement I and Statement II are false
Both Statement I and Statement II are true
Explanation
The +3 oxidation state of lanthanide is most
stable and therefore lanthanide in +4 oxidation
state has strong tendence to gain eā
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 eā and converted into +3 oxidation state therefore act as strong reducing agent.
$$ \therefore $$ 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 eā and converted into +3 oxidation state therefore act as strong reducing agent.
$$ \therefore $$ EuSO4 act as a strong reducing agent.
