What are the values of m and n in the anionic species `[V(CO)_(m)]^(n-)` if it is fllowing Sidwick `EAN` rule and having octahedral shape ? .

Answer» Correct Answer - 6,1
`[V(CO)_(m)]^(n-) , V(Z =22) = 3d^(3) 4s^(2)`
For octedral shape of complex `m =6`
`EAN` of `V =Z +(-ve "charge") +2r m =36)`
`= (22 + n + 2 xx 6)= 36implies n =1` .
