When SCN^(-) is oxided to an aqueous solution is

Answer»

`|Fe(OH_(2))_(2)(SCN)^(2)|^(2+)`
`|Fe(OH_(2))_(5)(SCN)|^(2+)`
`|Fe(OH_(2))_(8)(SCN)|^(2+)`
`|Fe(OH_(2))_(2)(SCN)|^(6+)`

Solution :`Fe^(3+) + SCN^(-) + H_(2)Orarr |Fe(H_(2)O)_(5)SCN|^(2+)` (Red colour)
i.e. `:.` HYBRIDIZATION is `sp^(3)d^(2)` outer ORBITAL (high spin octahedral.
