Answer:
The oxidation number for chlorine in HClO2 is plus three because oxygen is more electronegative than chlorine and is assigned negative two for each oxygen and hydrogen had a plus one. The sum of oxidation numbers is equal to the charge on the molecule, in this case zero.

Answer:
oxidation number of H is +1 and that of O is -2
and let the oxidation number of Cl be x
HClO3 is a neutral molecule
so, by adding all the oxidation number we get 0
(+1)+x+3(-2) = 0
+1+x-6=0
x = +6-1
x =+5
Therefore oxidation number of chlorine in HClO3 is +5
