oxidation state of oxygen in of2 is

0

The oxidation number of oxygen in compounds is usually -2. –2 on each of them, which also means the C has to be a +4 because of rule #1. Oxygen is given the oxidation number of –2 when combined with other elements. Therefore, a compound that readily loses its electrons is easily oxidised. So if it is oxygen by itself (e.g., O2) then the oxidation number/state is 0. The oxidation number of fluorine is always -1 but the oxidation number of chlorine differs in different compounds.

In oxidation state problems, group (I) metals (alkali metals) ALWAYS have oxidation state +1. For example, when iron is expressed as Fe 3+, it tells us that it has an increased oxidation state and has lost 3 electrons. But in peroxides, the oxidation state of O is -1. Fluorine is the most electronegative element and will pretty well always be found as -1 (except in F2, of course). Each oxygen atom contributes equally to the overall oxidation state, so the oxidation state of each individual oxygen is -0.5. Want to see the step-by-step answer?

Oxidation state of oxygen in H202, and OF2, is (1) +1,-1 (2) -2,+2 (3) +2 +1 (4) -1,+2 2 See answers manish19307 manish19307 1 is the correct answer . Relevance. and why or why not ? Chlorine in compounds with fluorine or oxygen : Because chlorine adopts such a wide variety of oxidation states in these compounds, it is safer to simply remember that its oxidation state is not -1, and work the correct state out using fluorine or oxygen as a reference. Oxygen is present, so it has a preferred oxidation state of -2 each. You can also calculate it as follows: iv) Group IIA metals have an oxidation state of +2, unless in their uncombined state. The oxidation number of hydrogen is -1 in compounds containing elements that are less electronegative than hydrogen, as in CaH 2. 9 months ago. Check out a sample Q&A here. !-1 in H2O2 +2 in OF2.
