Question

Manganese can readily form the covalent green oil $Mn_2O_7$ in the extreme $+7$ oxidation state. However, its highest corresponding stable fluoride is only Manganese(IV) fluoride ($MnF_4$). Why is oxygen definitively capable of stabilizing higher oxidation states than fluorine?

Answer: C

💡 Solution & Explanation

While fluorine is the most electronegative element, oxygen's unique ability to form stable $\pi$ -bonds (double bonds) with the vacant $d$ -orbitals of the metal allows it to stabilize higher charge densities and extreme oxidation states (like $+7$ and $+8$).
