Questions
The main reason for larger number of oxidation state exhibited by the actinides than that corresponding lanthanides, is
a
lesser energy difference between 5f and 6d orbitals than between 4f and 5d-orbitals
b
larger atomic size of actinides than the lanthanides
c
more energy difference between 5f and 6d orbitals than between 4f and 5d-orbitals
d
greater reactive nature of the actinides than the lanthanides.
detailed solution
Correct option is A
As both 5f and 4f orbitals have similar shapes and they resemble in their angular part of the wave functions. But 4f orbitals is much more penetrated than 5f orbital towards nucleus.Talk to our academic expert!
