Question

Quizplus · Accepted Answer

In an SN1 mechanism, during the second step the nucleophile attacks the carbocation formed in the first step. The dissociation step (noted in choice A) is the slow step in an SN1 mechanism, but not in an SN1 mechanism. Primary alkylhalides (noted in choice C) are not the best substrates for SN1 reactions, as they form stable carbocations too slowly. The hydroxyl group (noted in choice D) is not a good leaving group in SN1, but rather in SN2 reactions. The configuration of the substrate is not necessarily retained in the product in SN1 reactions (noted in choice E).
