Write down t he IUPAC name for each of the following complexes and indicate the oxidation state, electronic configuration and coordiantion number. Also give magnetic moment of the complex.
`K[Cr(H_(2)O)_(2)(C_(2)O_(4))_(2)]*2H_(2)O`

Text Solution

Verified by Experts

Potassium diaquadioxalatochromate(III)
hydrate C.N = 6
Shape = octahedral
Oxidation state (O.S) of Cr
`x+0+2xx(-2)=-1`
`x=3`
Electronic configuration of `Cr^(3+)=3d^(3)rArrt_(2g)^(3)e_(g)^((0)`
Unpaired electrons (n) = 3
Magnetic moment `(mu)=sqrt(n(n+2))` BM
`=sqrt(3xx5)=3.87` BM
