Which one of the following lanthanides exhibits +2 oxidation state with diamagnetic nature?

(Given Z for Nd = 60, Yb = 70, La = 57, Ce = 58)

Correct Option - 2


Detailed Solution:

La⁺² (z = 57) = 5d¹

Ce⁺² (z = 58) = 4f²

Nd⁺² (z = 60) = 4f⁴

Yb⁺² (z = 70) = 4f¹⁴

Yb⁺² has no unpaired electrons thus diamagnetic in nature.
