There are three unpaired electrons in `[Co(H_(2)O)_(6) ]^(2+)` and calculated value of magnetic moment is 3 · 87 BM which is quite different from the experimental value of 4·40 BM. 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

d-d transition.

There are 3 unpaired electrons in [Co(H_(2)O)_(6)]^(2+) and calculated value of magnetic moment on the basis of sqrt(n(n+2)) is 3.87 BM , which is much lower than the experimental value of 4.4 BM . The reason for this difference is due to :

Transition metals and many of their compounds show paramagnetic behaviour where there are unpaired electron or electrons. The magnetic moment arises from the spin and orbital motions in ions or molecule. Magnetic moment of n unpaired electrons is given as mu=sqrt(n(n+2)) Bohr magneton Magnetic moment increases as the number of unpaired electrons increases. Q.
