Vedclass · Answer

(D) The ability of oxygen to form multiple bonds with metals is the key factor.
In $Mn_2O_7$,each $Mn$ atom forms multiple bonds with oxygen,which stabilizes the $+7$ oxidation state.
In contrast,fluorine can only form single bonds.
To achieve a $+7$ oxidation state with fluorine,$7$ fluorine atoms would need to surround the $Mn$ atom,which causes significant steric crowding and makes the compound unstable.
Therefore,oxygen's ability to form $p\pi-d\pi$ multiple bonds allows it to stabilize higher oxidation states compared to fluorine.

The highest oxidation state of manganese in fluoride is $+4$ $(MnF_4)$,but the highest oxidation state in oxides is $+7$ $(Mn_2O_7)$ because __
