Solution:Concept- De-electronation is the process in which electrons are lost and electronation is the process in which electrons are gained.
Oxidation is defined as the gain of an oxygen atom or the loss of electrons.
Thus, oxidation is shown as-
On the other hand, reduction is defined as the loss of oxygen atom or gain of hydrogen atom or the gain of electrons.
Thus, reduction is shown as-
As during oxidation, electrons are lost, thus it is a process of de-electronation.
Hence, the correct option is (1).
