[Fe(H_(2)O)_(5)NO]^(2+) is a complex formed during the brown ring test for NO_(3)^(-) ion. In this complex,

Answer»

there are THREE unpaired ELECTRONS so that its magnetic moment is 3.87 B.M.
NO transfers its electron to `Fe^(2+)` so that IRON exists as Fe (I) and NO as `NO^(+)`
the COLOUR is because of charge transfer
all of the above statements are correct

Solution :`{:(" "":"overset(.)(N)=UNDERSET(..)(O): rarr : overset(+)(N) = underset(..)(O) : + e^(-)),(Fe^(2+)+e^(-) rarr Fe^(+)):}`

`therefore` Magnetic moment of `Fe^(+) = sqrt(n(n+2))` BM
`=sqrt(3xx5)BM = 3.87 BM`
All statements are correct.
