The complex [Fe(H_(2)O)_(5)NO]^(2+) is formed in Brown ring test for nitrates select correct statement for the complex ?

Answer»

Hybridisation of iron is `sp^(3)d^(2)`
Iron and nitrosyl has +1 oxidation state
It has magnetic moment of 3.87 B.M.
All are correct

Solution :In `[FE(H_(2)O)_(5)NO]^(+2)`
`Fe^(+)=3d^(6)4s^(1)`
in presence of ligand `Fe^(+)=3d^(7)4s^(0)`
hybridisation `=sp^(3)d^(2)`,
magnetic moment.s = 3.87 B.M.
