The highest Manganese fluoride is

Assertion : The highest manganese fluroide is MnF_(4) and the highest oxide is Mn_(2) O_(7) . Reason : In Mn_(2) O_(7) , each Mn is tetrahedrally surrounded by O's including Mn-O-Mn bridge.

The highest Mn fluoride is MnF_(4) where as the highest oxide is Mn_(2)O_(7) Why?

Give reason for the following : Although ‘F’ is more electronegative than 'O', the highest Mn fluoride is MnF_4 , whereas the highest oxide is Mn_2O_7 .

Fluoride ion

Fluoride ion

Highest oxidation state of manganese in fluoride is + 4 (MnF_(4)) but highest oxidation state in oxides is + 7 (Mn_(2)O_(7)) , because -
