Question

The complex [Fe(H2O)5NO]2+ ion has a magnetic moment of 3.87 B.M. This is indicative of the fact that

Solution

Correct option is

There are three unpaired electrons in the central atom which is due to transfer of odd electron of  to Fe2+

 

.  

(unpaired electrons). The complex may be regarded as a high spin d7complex of Fe+ and No+
