Oxidative cleavage of alkenes takes place in the presence of _ ?

Correct answer: C. Warm alkaline KMnO4

  • A. Acidic cold KMnO4
  • B. Warm Acidic KMnO4
  • C. Warm alkaline KMnO4
  • D. Alkaline cold KMnO4

Explanation

Oxidative cleavage of alkenes typically occurs in the presence of hot alkaline KMnO4 (potassium permanganate).When alkenes are treated with hot alkaline KMnO4, the double bond of the alkene is oxidized, resulting in the cleavage of the carbon-carbon double bond. The reaction generates two carbonyl compounds, which may further undergo subsequent reactions depending on the specific conditions and nature of the alkene.On the other hand, hot acidic KMnO4 (sodium or potassium permanganate in a basic solution) is commonly used for the oxidative cleavage of alkynes. It leads to the formation of carboxylic acids or carbon dioxide, depending on the substituents present in the alkyne.

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.
