Identify the product obtained when alkenes are oxidised with KMnO ₄ in dil. H ₂ SO ₄ .

Step-by-step solution

Strong oxidative cleavage of alkenes with potassium permanganate in dilute sulfuric acid cleaves carbon-carbon double bonds. The products depend on substitution patterns: vinylic carbons with hydrogen atoms oxidize to carboxylic acids ( alkanoic acids ), while fully substituted vinylic carbons oxidize to ketones ( alkanones ). Under these strongly oxidizing conditions, alkanals (aldehydes) are unstable intermediates that undergo further oxidation to carboxylic acids. Alkanols are not formed, as they result from mil
