Question

Which process involves the transfer of electrons?

  1. Double replacement
  2. Neutralization
  3. Oxidation - reduction
  4. Sublimation

hintHint:

Oxidation is loss of electron and reduction is gain of electron so transfer of electrons occurs in a redox reaction

The correct answer is: Oxidation - reduction


    Oxidation is the loss of electrons during a reaction by a molecule, atom or ion. Oxidation occurs when the oxidation state of a molecule, atom or ion is increased. The opposite process is called reduction, which occurs when there is a gain of electrons or the oxidation state of an atom, molecule, or ion decreases.

    Oxidation - reduction process involves the transfer of electrons.
