Since all lanthanides and actinides belong to group IIIB or 3rd group they have common oxidation state of +3 as the most stable state. In addition to +3, they also show +2 and +4 states also. M+2 states they are good reducing agents. Actinides show higher oxidation states of +5, +6 and +7. For them +3 state is not the most stable state especially for the flfst four elements
Based upon the information above answer the following questions
Lanthanides which show powerful reducing action in +2 state

A

La, Od, HO

B

Er,Lu,Eu

C

Th,Yb,Ce

D

Nd,Sm,Tb

Text Solution

Verified by Experts
