There are three unpaired electrons in 
and calculated value of magnetic
moment is 3.87 B.M which is quite different from the experimental value of 4.40 B.M. This is because of
A
increase in number of unpaired electrons
B
some contribution of the orbital motion of the electron to the magnetic moment
C
change in orbital spin of the electron
D
transition
Text Solution
Verified by ExpertsThe correct answer is:
B
, where, 
The experimental value of magnetic moment is 
due to some contribution of the orbital motion of electron to the magnetic moment.
