Question

In free radical reaction, free radicals are formed at ?

Answer 1

Answer:

Free radical in the free radical reaction is formed in the initiation phase.

Explanation:

The radical reaction mechanism includes three steps as follows:

1. Initiation phase

2. Propagation phase

3. Termination phase

1. Initiation phase

In the initiation phase radical is generated using UV light or heat via homolytic or heterolytic cleavage.

2. Propagation phase

In the propagation phase radical attacks the stable molecule to form a compound.

3. Termination phase

In the termination phase, two radicals combine to stop the reaction.

For example, Reimer-Teimann reaction goes through the radical mechanism.
