Vedclass · Answer

(D) Step $1$: Calculate the oxidation state of the metal in each species.Step $2$: For $MnO_4^{-}$, let the oxidation state of $Mn$ be $x$. $x + 4(-2) = -1 \implies x = +7$.Step $3$: For $[Cr(CN)_6]^{3-}$, let the oxidation state of $Cr$ be $x$. $x + 6(-1) = -3 \implies x = +3$.Step $4$: For $Cr_2O_3$, let the oxidation state of $Cr$ be $x$. $2x + 3(-2) = 0 \implies 2x = 6 \implies x = +3$.Step $5$: For $CrO_2Cl_2$, let the oxidation state of $Cr$ be $x$. $x + 2(-2) + 2(-1) = 0 \implies x - 4 - 2 = 0 \implies x = +6$.Step $6$: Thus, $CrO_2Cl_2$ contains the metal in the $+6$ oxidation state.

Identify the species having a metal atom in the $+6$ oxidation state from the following:
