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

MnF_(7) is not stable while Mn_(2)O_(7) is stable.

The highest oxidation state of Mn is shown by

(a) Give reasons for the following : (i) Mn^(3+) is a good oxidising agent. (ii) E(M^(2+)//M)^(@) values are not regular for first row transition metals (3d series). (iii) Although 'F' is more electronegative then 'O', the highest Mn fluoride is MnF_(4) whereas the highest oxide is Mn_(2)O_(7) . Complete the following equations : (ii) 2 CrO_(4)^(2-)+2H^(+)rarr (ii) KMnO_(4)overset("heat")rarr
