Quizplus · Accepted Answer

Cyclopentyl hydrogen sulfate (B) is the major product of the reaction between cyclopentanol and sulfuric acid. This is because the sulfuric acid protonates the hydroxyl group of the alcohol, making it a better leaving group. The resulting carbocation then undergoes a nucleophilic attack from the sulfate ion present in the sulfuric acid to form the cyclopentyl hydrogen sulfate. The other options are not major products of this reaction.
