Hydrolysis of cyano group by an aqueous acid results into:
Correct answer: A. Carboxylic Acid
- A. Carboxylic Acid
- B. Acid Amide
- C. Cyanohydride
- D. Formaldehyde
Explanation
A is correct as hydrolysis of a cyano group results in the formation of a carboxylic acid (fact)B is incorrect as acid amide is not a product of hydrolysis of a cyan groupC is incorrect as cyanohydride is a product of addition of hydrogen cyanide to carbonyl compounds.D is incorrect as oxidation of alcohol results in formaldehyde.

About Nomenclature, Structure and Preparation
Carboxylic acids are prepared by oxidising primary alcohols or aldehydes, hydrolysing nitriles, esters and amides, and carbonating suitable organometallic compounds. Their structures, IUPAC naming, resonance stabilisation and acidic character explain why carboxylic acids differ from alcohols and phenols, despite all containing oxygen and hydrogen.
