Carboxylic acids can be reduced to corresponding alcohols. Which of the following reagent can be used for this purpose?
Correct answer: B. LiAlH4
- A. KMnO4
- B. LiAlH4
- C. K2Cr2O4
- D. H2SO4
Explanation
For this reaction to take place, you need the proper reducing agent, which is only LiAlH4 i.e. option B. (NOTE: NaBH4 is not a strong enough reducing agent to reduce carboxylic acids, but LiAlH4 is.)Options A, C, and D; all describe OXIDISING agents.

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.
