Question

Quizplus · Accepted Answer

In an S_N1 mechanism, the slow step is the formation of a carbocation, which is then attacked by a nucleophile in the second step. Choice A is incorrect because the slow step produces a carbocation, not a carbanion. Choice C is incorrect because primary alkylhalides are more likely to undergo SN2 reactions instead of SS1 reactions. Choice D is incorrect because the hydroxyl group is a poor leaving group in SS1 reactions. Choice E is incorrect because the carbanion formed in the first step would be too reactive and would not form in significant amounts.
