Which of the following causes complete reduction of a carboxylic acid into alkanes?
Correct answer: C. HI/P
- A. H2/Ni
- B. Pd/C
- C. HI/P
- D. LiAlH4
Explanation
"HI" reduces carboxylic acid to alkanes in the presence of "P" as a catalyst as it is a strong reducing agent.

About Reactivity of Carboxylic Acids
Carboxylic acids show acidic behaviour because their carboxylate ions are resonance-stabilised, and electron-withdrawing groups can change their strength. Reactions include neutralisation, esterification, formation of acid chlorides and amides, reduction, decarboxylation and substitution at the acyl carbon, which differs from the reactions of phenols.
