Question

Which is not a characteristic of free radical chain reaction?

• A. It produces a mole of product for a mole of free radical initiated
• B. It gives the product derived from the most stable radical
• C. It may be initiated by peroxides
• D. It may be initiated by light or heat.

Answer 1

Answer: (A)

It produces a mole of product for a mole of free radical initiated

The statement, "It produces a mole of product for a mole of free radical initiated" is not a characteristic of free radical chain reaction.

Free radicals just initiate the reaction, propagation steps producing products don't effectively consume free radicals.

Thus, the amount of free radical initiated is very small as compared to the amount of product.
