Step 1
What is the name of the mechanism of this reaction?
Answer
The mechanism of the reaction where 2-bromopropane reacts with bromine to form 2,2-dibromopropane is known as free-radical substitution.
In this reaction, the bromine molecule undergoes homolytic cleavage to form two bromine radicals, which can then react with the alkyl bromide to produce the dibrominated compound. The free-radical mechanism is characterized by three main steps: initiation, propagation, and termination.
