Question

Question: Using Mechanism 15.1 as a guide, write the mechanism for the reaction of CH₄with Br₂ to form CH₃ Br and HBr. Classify each step as initiation, propagation, or termination.

Short answer

Answer

Step-by-step solution

Radical halogenation of alkanes

The first step is initiation that involves the hemolysis cleavage ofform two radicals.

The second step is propagation that involves the attack of the radical to the alkane to form alkyl and radical.

The third step is termination that involves the reaction of radicals together to stop the chain.

 Step 2: Explanation

The steps involved in the reaction are shown below:

Initiation:

Initiation reaction

Propagation:

Propagation reaction

Termination:

Termination reaction
