In how many of the following complex ions, the central metal ions use (n-1)d, ns and np orbitals for hybridisation ? [Mn(CN)_6]^(4-), [Ni(NH_3)_6]^(3-), [Co( o x)_3]^(3-), [Cu(NO_2)_6]^(4-), [AgF_4]^(-), [Ni(CN)_4]^(2-), [PdCl_4]^(2-), [PdCl_4]^(2-), [Pd(CN)_4]^(2-),[Co(SCN)_4]^(2-)

Answer»


Solution :`[Mn(CN)_6]^(4-)-3d^(5),d^2sp^(3),+2` oxidation state
`[Ni(NH_3)_6]^(2+)-3d^(8),SP^(3)d^2,+2` oxidation state
`[CO(o x)_3]^(3-)-3d^(6),d^2sp^(3),+3` oxidation state
`[Cu(NO_2)_6]^(4-)-3d^(9),sp^(3)d^2,+2` oxidation state
`[AgF_4]^(-)-4d^(8),dsp^(2),+3` oxidation state
`[Ni(CN)_4]^(2-)-3d^(8),dsp^(2),+2` oxidation state
`[PbCl_4]^(2-)-4d^(8),dsp^(2-),+2` oxidation state
`[Pb(CN)_4]^(2-)-4d^(8),dsp^(2-),+2` oxidation state
`[Co(SCN)_4]^(2-)-3d^(7),sp^(3-),+2` oxidation state
