Question: 112
7. The reduction of a carboxylic acid using lithium aluminum hydride will yield what final product?
- A. An aldehyde
- B. An ester
- C. A ketone
- D. An alcohol
Correct Answer: D
Explanation:
Lithium aluminum hydride (LiAlH4 or LAH) is a strong reducing agent. LAH can completely reduce carboxylic acids to primary alcohols. Aldehydes are intermediate products of this reaction; therefore, choice (A) is incorrect. The other compounds are not created through the reduction of a carboxylic acid.
