Concept explainers
Interpretation:A reasonable rate expression corresponding to chlorination of methane reaction should be proposed.
Concept introduction:The mechanism for monochlorination comprises of three stages illustrated as follows:
Step 1- Initiation via homolytic cleavage of
Step 2: Propagation: In the first of the propagation steps
radical generated from step 1 abstracts hydrogen radical from methane as follows:
In subsequent propagation step chloromethyl radical abstracts
Step3: Termination: Radicals generated in propagation steps get quenched upon the combination with one another. Thus termination steps are essentially the radical− radical combination illustrated as follows:
