1Oxidation involves loss of electron whereas reduction involves gain of electrons. A redox reaction is one in which a reductant is oxidised to lose electrons which are then taken up by an oxidant to get itself reduced. Oxidation-reduction occur simultaneously. The redox changes are of three types:
1. Intermolecular redox
2. Intramolecular redox and
3. Disproportionation
In a conjugate pair of redox, the one having higher oxidation number acts as oxidant and the other is its conjugate reductant.
The reaction, \( 2 \mathrm{Mn}_{2} \mathrm{O}_{7} \longrightarrow 4 \mathrm{MnO}_{2}+3 \mathrm{O}_{2} \) is an example of:
(A) disproportionation
(B) intermolecular redox
(C) intramolecular redox
(D) non redox
