Question -


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


 

Options:
A .   It gives the major product from the most stable free radical
B .   It is usually sensitive to a change in solvent polarity
C .   It proceeds in three main steps - initiation, propagation and termination
D .   It may be initiated by U.V. light
Answer: Option B
:
B
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.
