Exhaustive reduction of a carboxylic acid yields as its ultimate product________________?
Show answer Hide answer
Answer: C. Alkane
Explanation
Exhaustive reduction of a carboxylic acid completely replaces the oxygen atoms with hydrogen, yielding an alkane. Strong reducing agents like hydroiodic acid with red phosphorus can achieve this complete deoxygenation. Removing all oxygen functionalities transforms the original carboxylic acid into the corresponding hydrocarbon. Carboxylic acids contain a carbonyl and a hydroxyl group attached to a hydrocarbon chain backbone. Reduction reactions typically proceed through alcohol and aldehyde intermediates before reaching the final alkane. Forcing reduction reactions requires aggressive chemical reagents and elevated reaction temperatures.
Organic synthesis pathways utilize reduction reactions to convert oxygen-rich feedstocks into simple hydrocarbons. Understanding functional group reactivity helps chemists design efficient routes for modifying organic molecules. Petrochemical industries study hydrocarbon derivatives to develop advanced synthetic fuels and materials. Alkenes contain double bonds and represent intermediate or alternative reduction states rather than exhaustive products. Alkynes possess triple bonds and are synthesized through distinct elimination reactions rather than acid reduction. Alcohol represents only an intermediate reduction stage rather than the ultimate product of exhaustive reduction.
