What are compelex reactions ? Name one complex reaction.

1.	What are compelex reactions ? Name one complex reaction.
Answer» A sequence of elementery reactions, reactants give the products, the reactions are called complex reactions. Eg: Oxidation of Ethane to `CO_(2) and H_(2)O` passes through a series of intermediate steps in which alcohol, aldehyde and acid are formed.
