Which of the following reagents will reduce butanoic acid to butanol?
Correct answer: A. LiAlH4
- A. LiAlH4
- B. LiAlH4.H2O
- C. Mg(BH4)2
- D. All of the above
Explanation
LiAlH4 is a strong reducing agent that can reduce carboxylic acids to primary alcohols like butanol.LiAlH4.H₂O is used only to quench the reaction after reduction, not as the reducing agent itself.Mg(BH4)2 and milder reagents like NaBH4 cannot reduce carboxylic acids effectively.

About Carboxylic Acids
Carboxylic acids are named and studied through the combined effects of the carbonyl and hydroxyl groups, their preparation, acidity and hydrogen bonding. Reactions include neutralisation, esterification, reduction and conversion into acid chlorides, anhydrides, esters and amides, with emphasis on how these derivatives interconvert.
