During the reduction of carboxylic acids into alkanes in the presence of HI/P, the COOH group is reduced to?
Correct answer: A. CH3
- A. CH3
- B. C2H6
- C. CH2
- D. None of these options are correct
Explanation
Carboxylic acids on reduction with HI and red phosphorus give alkanes.During this reduction, the COOH group is reduced to CH3. CH3COOH + 6HI → CH3-CH3 + 2H2O + 3I2Hence, A is the correct option.

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.
