$+3$

Vedclass · Answer

(C) Let the oxidation number of $Pt$ be $x$.The complex is $[Pt(C_2H_4)Cl_4]^-$.$C_2H_4$ (ethylene) is a neutral ligand with an oxidation number of $0$.$Cl$ is a chloro ligand with an oxidation number of $-1$.The overall charge on the complex is $-1$.Therefore,the equation is: $x + 0 + 4(-1) = -1$.$x - 4 = -1$.$x = +3$.Thus,the oxidation number of $Pt$ is $+3$.
