Question

Among the following, identify the species with an atom in +6 oxidation state

Options

• \[\ce{MnO^{-}4}\]

• \[\ce{Cr(CN)^{3-}4}\]

• \[\ce{NiF^{2-}6}\]

• CrO₂Cl₂

Answer 1

CrO₂Cl₂ 

Explanation:

\[\ce{MnO^{-}4}\] (O.S. of Mn +7)

\[\ce{Cr(CN)^{3-}6}\] (O.S. of Cr +3)

\[\ce{NiF^{2-}6}\] (O.S. of Ni +4)

CrO₂Cl₂ (O.S. of Cr +6)
