Instructions: $\alpha$,$\beta$-Unsaturated aldehydes and ketones can undergo reaction with nucleophiles at the $\beta$ carbon, as shown below. Use this information to answer the following question(s). 
-Refer to instructions. This reaction is called a(n) _____ reaction.

Quizplus · Accepted Answer

The reaction described is a conjugate addition, which involves the addition of a nucleophile to the β-carbon of an unsaturated carbonyl compound. Choice A is the only option that correctly identifies the type of reaction. Choices B and C are not applicable because they do not involve the specific mechanism described, and choice D is incorrect because it refers to addition to adjacent carbons rather than the β-carbon.
