Question

Oxidation number of oxygen in which of the following compound is zero
HOCL
HOF
H₂O₂
HIO₄

Answer 1

Answer:

HOCl (Hypochlorous acid) ionises as OH- + Cl+

This means, OH- so, O will have -2 oxidation number because H is always in +1 oxidation number

H2O2 (Hydrogen peroxide), Each H is +1 so each O will be -1

HIO4 Here in Periodic acid, I(iodine) is in +7 oxidation state and H is +1 so, each Oxygen is -2.

In HOF(Hypofluorous acid) H is +1 as always, and Fluorine being the most electronegative element cannot exist in any other oxidation state except -1 and 0 in only case of F2 gas.

So, here oxygen will have to be in 0 oxidation state.

HOCl case is different as there Cl can be in +1 oxidation state but in HOF, F can't have +1 oxidation state being the most electronegative element.

Answer 2

Answer:

hof

Explanation:

HOF

1+x+(-1)=0

x+0=0

x=0

☆Oxidation no. of O2 in HOF=0
