B)an S_N2-type reaction involving the protonated alcohol as the substrate. C)an E1-type reaction involving the protonated alcohol as the substrate. D)an E2-type reaction involving the protonated alcohol as the substrate. E)an epoxidation reaction.

Question

Quizplus · Accepted Answer

The reaction between 1-pentanol and HBr is an S_N2-type reaction because 1-pentanol is a primary alcohol, which typically undergoes bimolecular nucleophilic substitution (S_N2) reactions. The protonated alcohol acts as the substrate, and the bromide ion acts as the nucleophile.
