Consider the statement:All decomposition reactions are not redox reactions....

Consider this statement: Is the equation

2KClO₃---à2KCl+3O₂ Intra molecular redox reaction?

Tell me correct answer

a)1,2 are correct

b)1 is correct,2 is wrong

c)1 is wrong,2 is correct

d)1,2 are wrong

Dear praneeth,

First statement is incorrect, as there are some rxn that are both decomsition and redox rxn

                        E.g.:  NH₄NO₂(s) → N₂(g) + 2 H₂O(g)

Now second statement is correct, as intra molecular reaction are those rxn in which species being reduced and oxidized belong to different element of same group.

In rxn,                          2KClO₃  ------> 2KCl+3O₂

Reduction:                  Cl⁺⁵ -----> Cl^-1

Oxidation:                   O^-2  ------> O⁰

As Cl & O getting reduce and oxidize respectively belong to same molecule hence it is called intra molecular reaction
