If 2-butene is treated with KMnO_4 , the product formed will be:
Correct answer: C. Butyric acid.
- A. Butanoic acid
- B. Propanoic acid
- C. Butyric acid.
- D. Acetic acid
Explanation
KMnO_4 is a strong oxidizing agent. When 2-butene is treated with KMnO_4 , it undergoes oxidative cleavage, breaking the double bond and forming two carboxylic acids. Since 2-butene has four carbon atoms, the resulting carboxylic acid will also have four carbon atoms, which is butyric acid (also known as butanoic acid).

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.
