Which reagent(s)will distinguish between cyclopentanol and cyclopentane?

Question

Quizplus · Accepted Answer

CrO3/H2SO4 or aqueous H2SO4 oxidizes primary alcohols to carboxylic acids, but has little effect on alkanes. Thus, the reaction will only occur with cyclopentanol, distinguishing it from cyclopentane. Choice A is not a real reagent. Choice B, KMnO4(cold), will oxidize alcohols, but can also oxidize alkanes under certain conditions, making it an unreliable reagent for distinguishing between the two compounds. Choice D, NaOH(aq), is a base and will not distinguish between the two compounds.
