Question:
Which of the following statements, is not characteristic of free radical chain reaction?
Which of the following statements, is not characteristic of free radical chain reaction?
Updated On: Jun 7, 2022
- It gives major product derived from most stable free radical
- It is usually sensitive to change in solvent polarity
- It proceeds in three main steps like initiation, propagation and termination
- It may be initiated by UV-light
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
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.
