Which fo the following reactions is an example of intramolecular redox

1.	Which fo the following reactions is an example of intramolecular redox reaction ?A. `CaCO_3 (s) rarr CaO(s) + CO_2(g)`B. `2 H_2O(l) rarr 2H_2(g) +O_2(g)`C. `2 NaH(s) rarr 2Na(s) +H_(2)(g)`D. `2 KClO_3 (s) rarr 2KCl(s) +3 O_2(g)`
Answer» Correct Answer - D `2 overset(+5)(Cl)overset(-2)(O_(3))(s) rarr 2K overset(-1)(Cl)(s)+3overset(0)(O_(2))(g)` It is an example of intramolecular redox reaction because oxygen of ` KClO_3` is oxidized (-2 to 0) while chlorine of ` KClO_3` is reduced (+5 to -1). It is different from disproportionation reaction as different elements (of the same species) are oxidized and reduced.
