Write the `IUPAC` nomenclature of the given complex along with its hybridisation and structure
`K_(2)[Cr(NO)(NH_(3))(CN)_(4)],mu =1.73.BM` .

Explanation

`K_(2)[Cr(NO)(NH_(3))(CN)_(4)]`
Its `IUPAC` name is potassium amminetetracyanonitrosochromate(I) The oxidation number of Cr is +1
Atomic number `=24`
`Cr =[Ar]3d^(5) 4ws^(1)`
`Cr^(o+) =[Ar]3d^(5)`
Give `mu = 1.73 BM`
`:. sqrt(n(+2)) =1.73`
or `n =1`(only one unpaired electron) After pairing
`d^(2)sp^(3)` hybridisation occurs Shape is octahedral
