MHT CET Chemistry Question (2026) — Solution

Step-by-step solution

Alkenes undergo oxidative cleavage when treated with a strong oxidizing agent like KMnO _4 in acidic medium (dilute H _2 SO _4). During this reaction, the carbon-carbon double bond is completely cleaved. A = CH - group is initially oxidized to an aldehyde (alkanal), which is highly susceptible to further oxidation under these conditions and immediately oxidizes to a carboxylic acid (alkanoic acid). For example: R - CH = CH - R ' KMnO _4 / H ^+ R - COOH + R '- COOH Thus, the final stable product formed is an alkanoic acid. Answer: Alkanoic acid
