Vedclass · Answer

(D) To find the oxidation state of the central atom,we assign oxidation numbers to the ligands:In $MnO_4^-$,$Mn + 4(-2) = -1 \implies Mn = +7$.In $Cr(CN)_6^{3-}$,$Cr + 6(-1) = -3 \implies Cr = +3$.In $NiF_6^{2-}$,$Ni + 6(-1) = -2 \implies Ni = +4$.In $CrO_2Cl_2$,let the oxidation state of $Cr$ be $x$. Since $O$ is $-2$ and $Cl$ is $-1$,we have $x + 2(-2) + 2(-1) = 0 \implies x - 4 - 2 = 0 \implies x = +6$.Therefore,the species with an atom in $+6$ oxidation state is $CrO_2Cl_2$.

Amongst the following,identify the species with an atom in $+6$ oxidation state.
