Which of the following is incorrect option ? {:(CuI_(2)+KI to K_(3)[CuI_(4)]),("complex salt"):}

Answer»

oxidation STATE of central ATOM decreases during the formation of complex.
Complex is tetrahedral.
Hybridisation of the complex is `SP^(3)`.
Hybridisation of the complex is `dsp^(2)`.

SOLUTION :`K_(3)[overset(+)CuI_(4)], I^( )C.F.S.E."is very small(since C.A. ALSO has low charge)"impliesC.N.=4 to sp^(3)`
