Oxidation number

Chemistry Level 1

The oxidation state, often called the oxidation number, is an indicator of the degree of oxidation of an atom in a chemical compound. Which of the following options states in correct order the oxidation numbers of the underlined atoms in the chemical reaction equation below? Fe ‾ 2 O 3 + 3 C ‾ O → 2 Fe ‾ + 3 C ‾ O 2 \underline{\text{Fe}}_2\text{O}_3+3\underline{\text{C}}\text{O} \to 2\underline{\text{Fe}}+3\underline{\text{C}}\text{O}_2

+2, +1, 0, +1 +3, +2, 0, +2 +3, +2, 0, +4 +3, +2, +3, +4

The oxidation number of an atom is the number of bonds it has with oxygen atoms in the compound. Oxygen atom has a valency of 2 or has 2 bonds. Therefore, there are 6 bonds with the 2 F e \ce{Fe} atoms in F e X 2 O X 3 \ce{Fe2O3} , so the oxidation number of the F e \ce{Fe} atom is +3. Similarly, the oxidation numbers of the rest are +2, 0 and +4.
