Which of the following statements is consistent with the mechanism for nucleophilic addition of aldehydes/ketones under basic conditions?

Question

Quizplus · Accepted Answer

In the mechanism for nucleophilic addition of aldehydes/ketones under basic conditions, the nucleophile attacks the carbonyl carbon to form a tetrahedral intermediate. This intermediate then undergoes a proton transfer to form an alcohol. Therefore, the correct order of steps is a nucleophilic attack followed by a proton transfer. Choice A is incorrect because the proton transfer occurs after the nucleophilic attack. Choice C is incorrect because there are two steps involved. Choice D is also incorrect because the proton transfer is necessary to form the alcohol.
