What is the oxidation number of BrO2?

Question

a) -1
b) +1
c) +2
d) +3

Please explain also. Thanks

yes, what is the oxidation number of Br in BrO2?

Answer 1

BrO2 is bromine superoxide, which would give Br an oxidation number of +1 and oxygen an oxidation number of -1/2 , which is the requirement for a superoxide. I say this because I have never known bromine to have a +2 or +4 oxidation state it its compounds, and in oxoacids, its oxidation numbers are odd (from +1 in the hypobromite to +7 in the perbromate). This is why I don't pick +2, which would make it bromine peroxide. I don't pick +3, because that would require that oxygen have an oxidation number of -1.5 , which is impossible. Hope this helps!

Answer 2

do you mean "what is the oxidation number of bromine in BrO2"?

then it will be the answer:-

Let x be the oxidation number of Br
and we knew that the oxidation number of O2 is -2 (but there are some exceptions) and the oxidation number of a compound (without charge) is 0.
Then...

x + (-2)2 = 0
x - 4 = 0
x = +4

so i'm very sorry to tell you that there is no answer for this question...if you intend to find the oxidation number of Br
