Question

compounds.
3. The oxidation number of oxygen in most
compounds is -2. However, we come across
two kinds of exceptions here. One arises
in the case of peroxides and superoxides,
the compounds of oxygen in which oxygen
atoms are directly linked to each other.
While in peroxides (e.g., H2O2, Na,02), each
oxygen atom is assigned an oxidation
number of -1, in superoxides (e.g., KO2,
RbO2) each oxygen atom is assigned an
oxidation number of -(Y2). The second
exception appears rarely, i.e. when oxygen
is bonded to fluorine. In such compounds​

Answer 1

ANSWER

in such compounds oxidation state of oxygen is +2 ( in OF22) , +1( in O2F2)

for example

compoumds of oxygen with flourine are OF2, F2O2

we know flourine has more electronegative then oxygen

so when compound have bond formation between oxygen and flourine then eletron shifts towards flourine.
