In the combination reaction, two reactants combine to form 1 product. Mg+N2→Mg3N2 So, A of list-I matches with (iii) of list-II. In the decomposition reaction, one reactant decomposes into multiple products. KClO3→KCl+O2 So, B of list I matches with (iv) of list II. A disproportionation reaction is a redox reaction in which one species undergoes both oxidation and reduction. Cl2→Cl−+ClO3− So, C of list I matches with (ii) of list II. When components of two ionic compounds are swapped, two new compounds are formed. This is double displacement reaction. AgNO3+CaCl2→CaNO3+AgCl2 So, D of list I matches with (i) of list II. Hence the correct match is A-(iii), B-(iv), C-(ii), D-(i)
