Question 1 Report

Which of the following is not correct about oxidation number convention? The oxidation number of a/an
Answer Details
The statement that is not correct about the oxidation number convention is "atom of a diatomic molecule is +2". The oxidation number of an atom in a diatomic molecule depends on the molecule, and can be either positive, negative or zero. For example, in the diatomic molecule HCl, the oxidation number of H is +1 and the oxidation number of Cl is -1. In the diatomic molecule O2, the oxidation number of each O atom is 0. Therefore, the correct answer is "atom of a diatomic molecule is +2"
