In acidic medium, changes
to
which has two
bonds. Oxidation state of
in
is:-
+5
+3
+6
-10
Exceptional configuration in '3d' series -
Due to half fill stable configuration is stable in
configuration at the place of
.
Similarly, stable with
at the place of
.
-
The reaction proceeds as follows:
In peroscide linkages, the ascidation state of each axygen atom is -1. Let O.S. of be x
Then, x-2-2*2=0
= x=+6
O.S, is +6
