Due to the presence of an unpaired electron, free radicals are:
- AChemically reactive
- BChemically inactive
- CAnions
- DCations
View written solutionFree
Correct answer: A
-
Understand the species
A free radical is a neutral species that contains an unpaired electron.
-
Effect of an unpaired electron
Because of the unpaired electron, the species is generally unstable and tends to react in order to pair that electron.
-
Check each option
-
A: Chemically reactive
True. Free radicals are highly reactive because of the unpaired electron. -
B: Chemically inactive
False. The unpaired electron makes them reactive, not inactive. -
C: Anions
False. Free radicals are not necessarily negatively charged; they are usually neutral species with an unpaired electron. -
D: Cations
False. Free radicals are not necessarily positively charged either.
