Question

Oxidation is a process of:
(A) Deprotonation
(B) Protonation
(C) Gain of electrons
(D) De electronation

Answer 1

Hint : oxidation is defined as the loss of electrons during a reaction. When oxidation takes place it results in the increase in the oxidation state. It is used to describe the reaction when an element combines with oxygen and results in an oxidation process.

Complete Step By Step Answer:
We can define oxidation in many ways. Let us see some of the definitions of oxidation.
In a chemical reaction, when loss of electrons takes place it is known as oxidation.
In a chemical reaction when oxygen is added to an element, it is known as oxidation.
In a chemical reaction when a proton is removed , it is known as oxidation.
When an oxidation state is increased it is known as oxidation.
Oxidation state is an hypothetical charge on an atom which indicates the degree of oxidation in a chemical reaction.
Now let us discuss the options given in the question
Deprotonation takes place when proton is removed from the bronsted lowry acid. It forms a conjugate base of the acid. In oxidation, removal of oroton takes place. Therefore option A is correct.
Protonation takes place when a proton is added in a chemical reaction. This is not the definition of oxidation. Therefore option B is incorrect.
When an atom gains an electron then the charge on that atom decreases. This process is known as reduction. Therefore option C is incorrect.
The loss of electrons in a chemical reaction is known as deprotonation. Therefore option D is correct
Hence the correct option is A and D.

Note :
Sometimes you might get confused between oxidising agents and oxidation. Oxidation is a process which oxidises itself in a chemical reaction whereas oxidising agents are the substances that itself get reduced and oxidised the other atoms. They sound similar hence you should know the meaning of both of them.
