$+2$

Vedclass · Answer

(B) Let the oxidation state of $Pt$ be $x$.$C_2H_4$ (ethylene) is a neutral ligand,so its charge is $0$.$Cl$ is a chloro ligand with a charge of $-1$.The overall charge on the complex $[Pt(C_2H_4)Cl_3]^-$ is $-1$.Setting up the equation: $x + (0) + 3(-1) = -1$.$x - 3 = -1$.$x = +2$.Therefore,the oxidation state of $Pt$ is $+2$.

The oxidation state of $Pt$ in $[Pt(C_2H_4)Cl_3]^-$ is .........
