Question

Which of the following statements is not characteristic of free radical chain reactions?

• A. It gives major product derived from most stable free radical
• B. It is usually sensitive to change in solvent polarity
• C. It proceeds in three main steps like initiation, propagation and termination
• D. It may be initiated by U.V. light

Answer 1

Answer: (B)

It is usually sensitive to change in solvent polarity

A free-radical reaction is any chemical reaction involving free radicals.

The major product is based on the most stable free radical.
These reactions usually involve 3 major steps: chain initiation, chain propagation and chain termination.
These are usually initiated by U.V light or other light sources which have enough energy to initiate the reaction.
