Free radicals can be produced by:
A)use of high temperatures.
B)irradiation with light.
C)reaction of a molecule with another free radical.
D)both use of high temperatures and irradiation with light.
E)use of high temperatures,irradiation with light,and reaction of a molecule with another free radical.

Question

Quizplus · Accepted Answer

Free radicals can be produced by all three mechanisms mentioned in options A, B, and C. High temperatures (option A) can cause the breakdown of molecules into smaller fragments, some of which might be free radicals. Irradiation with light (option B) can generate free radicals by exciting atoms or molecules to a higher energy state, leading to the formation of reactive species. Finally, a molecule can react with another free radical (option C) to form new radicals. Therefore, the best choice is option E, which includes all three mechanisms.
