Question

Arrange the following steps as they occur (first to last) during the free radical mechanism of polymer formation I. Chain propagation II. Chain initiation III. Chain termination

• A. I, II, III
• B. II, I, III
• C. III, I, II
• D. I, III, II

Answer 1

The correct option is B II, I, III

First step is chain initiation, where a free radical is formed

Second step is chain propagation, where the free radicals start forming chains by combining appropriately

Third and last step is chain termination, where the chain formation stops and the polymerized product is formed.
