Oxygen has the ability to form multiple bonds.

Vedclass · Answer

(B) The highest stable fluoride of manganese is $MnF_4$,while the highest oxide is $Mn_2O_7$. Oxygen has the ability to form $p\pi-d\pi$ multiple bonds with transition metals. This ability allows oxygen to stabilize the $+7$ oxidation state of manganese in $Mn_2O_7$ and $MnO_4^-$. Fluorine,being highly electronegative but unable to form multiple bonds,cannot stabilize the $+7$ oxidation state of manganese to the same extent.

The highest stable $Mn$ fluoride is $MnF_4$,whereas the highest $Mn$ oxide is $Mn_2O_7$. This is due to $-$
