Which of the following mechanism steps is required in the creation of epoxides from halohydrins?

Question

Quizplus · Accepted Answer

The formation of epoxides from halohydrins involves an intramolecular nucleophilic substitution reaction, where the hydroxyl group is deprotonated to form an alkoxide ion, which then attacks the adjacent carbon bearing the halogen, leading to the formation of the epoxide. This requires a proton transfer step to deprotonate the hydroxyl group.
