Question

Assume a single Br replacement in the reaction of methane and Br2. Use a structural diagram to show the products of the reaction between CH4 and Br2.

Answer 1

Answer: The answer is actually

H

H - C - Br + HBr

b

Step-by-step explanation:

Usually it is all H, but they asked for Br_2 This time

Answer 2

A detail reaction mechanism that is operative during the reaction methane and bromine gas is shown below.

In present mechanism, Br2 undergoes homolytic bond fission under irradiation with UV light. This results in generation of two Br· free radicals.

This, this free radical abstracts H· from methane to form HBr. This process in turn generates methyl radical.

Methyl radical combines with other Br· to form bromomethane.

UV irritation in present reaction systems, initiates chain of events
