All of the following methods are used to prepare carboxylic acids EXCEPT:
Correct answer: D. By the reduction of aldehydes
- A. By the oxidation of alcohol
- B. By acid hydrolysis of alkane nitrile
- C. By the reaction R-Mg-Br with CO2 followed by acid hydrolysis
- D. By the reduction of aldehydes
Explanation
In fact, by the reduction of aldehydes alcohols are obtained instead of carboxylic acids.While its oxidation gives Carboxylic Acids.

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.
