Question
Chemistry Question on reaction mechanism
Which of the following statements, is not characteristic of free radical chain reaction?
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 UV-light
Answer
It is usually sensitive to change in solvent polarity
Explanation
Solution
Free radical chain reactions occur mainly in non-polar compound or compounds, which give radicals by homolytic fission (often in presence of UV-light). These reactions may even occur in gaseous state (i.e., they need no solvent). Also these reactions proceeds in three main steps i.e., initiation, propagation and termination.
