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

Answer»

Fluorine is more ELECTRONEGATIVE than oxygen
Fluorine does not possess d-orbitals
Fluorine stabilises lower oxidation state
In COVALENT compounds fluorine can form single bond only while oxygen FORMS DOUBLE bond
