Which of the following statements is correct for oxidation reaction?
Which of the following statements is correct for oxidation reaction?
The correct option is D All the above statements are correct.
Oxidation reaction:
Reaction which involve the addition of oxygen to a species is called oxidation reaction. Oxidation can also be defined as the removal of electron causing an increase in oxidation of the species.
(A) Electronegative elements or radicals attract electrons. When it is added to an element , it attracts the shared pair of electrons towards itself thus reducing the electron density in the other element. Therefore, the elements loses electrons. Reduction of electron density is oxidation. Therefore, addition of electronegative element to an element causes its oxidation. option (A) is true.
(B) Hydrogen is an electropositive element. When it forms bond with another element, the shared pair of electron remains with the other element. Therefore, when a hydrogen is removed from a compound, there is a loss of electron density from the other element and therefore, it is oxidized. Option (B) is true.
(C) When an electropositive atom forms a covalent bond, the shared pair of electron remains with the other element causing an increase in electron density of the other element. Therefore when an electropositive atom or radical is removed, the electron density of the other element is decreased which is oxidation. Option (C) is true.
Since the statements in all the options are true, the correct option is (D) All the above statements are correct.
