Question

Quizplus · Accepted Answer

Radical species have unpaired electrons. In option A, there are no unpaired electrons as all the electrons are paired. Option B and D have the presence of sulfur and phosphorous, respectively, which can have a variety of oxidation states and therefore can exist as both radical and non-radical species. Option C only contains nitrogen, oxygen, and sulfur, all of which can form radicals, making it the best choice for a radical species.
