In the previous post, we discussed the reduction of carbonyl compounds such as aldehydes, ketones, acids, esters, and acid chlorides, covering the appropriate reducing agents, the step-by-step mechanisms, and key concepts involved in these transformations. This post serves as a summary with practice problems designed to reinforce your understanding and help you apply the reactions of carbonyl reductions in various contexts.
