An aldehyde and alcohol can react to form a

Question

Quizplus · Accepted Answer

The reaction between an aldehyde and alcohol leads to the formation of a hemiacetal. The reaction involves the nucleophilic addition of an alcohol to the carbonyl group of the aldehyde, followed by the loss of a water molecule. The resulting compound has a hemiacetal functional group, which contains an -OH group and a -OR group (from the alcohol). Choices A and B (hemialdol and hemiketal, respectively) are incorrect because they refer to different reaction products involving different starting materials (ketones in the case of hemiketals and aldehydes in the case of hemialdols). Choice D (all of the answers are correct) is incorrect because only choice C (hemiacetal) applies to the given reactants.
