Stepwise Mechanism for the Given Reaction

Introduction:

Chemical reactions are the processes in which one or more substances, the reactants, are transformed into one or more different substances, the products. The study of chemical reactions and their mechanisms is known as chemical kinetics. A reaction mechanism is a detailed description of the steps by which a chemical reaction takes place. It explains the sequence of elementary steps that lead to the formation of products from reactants.

Stepwise Mechanism:

The stepwise mechanism for the given reaction is as follows:

Step 1: Initiation

Initiation Step

In the initiation step, a free radical is generated. This can be done by homolytic bond cleavage, which is the breaking of a bond in a molecule to produce two free radicals. For example, the following reaction shows the homolytic bond cleavage of a hydrogen-hydrogen bond:

H2 → 2H·

Step 2: Propagation

Propagation Step

In the propagation step, the free radical attacks a molecule of the reactant, leading to the formation of a new free radical and a product molecule. For example, the following reaction shows the propagation step in the reaction between hydrogen and chlorine:

H· + Cl2 → HCl + Cl·

Step 3: Termination

Termination Step

In the termination step, two free radicals combine to form a stable molecule. For example, the following reaction shows the termination step in the reaction between hydrogen and chlorine:

2Cl· → Cl2

Overall Reaction:

The overall reaction is the sum of the individual steps in the mechanism. In the given reaction, the overall reaction is:

H2 + Cl2 → 2HCl
