Which of the following statements is correct for oxidation reaction?

1. Loss or removal of electron.
2. Removal of hydrogen atom.
3. Removal or loss of electropositive radical or element
4. All the above statements are correct

Correct answer: All the above statements are correct

Solution

Oxidation can be defined as loss of electrons, removal of hydrogen, or loss of an electropositive radical/element. Since each statement describes a valid form of oxidation, the inclusive option is correct.
