What product is formed by the controlled oxidation of a secondary alcohol (such as propan-2-ol) with acidified potassium dichromate?
Answer and explanation
Correct answer: D. Ketone
Secondary alcohols have two alkyl groups attached to the carbinol carbon; oxidation removes two hydrogen atoms to yield a ketone (propanone), which resists further oxidation under standard conditions. Primary alcohols oxidize to aldehydes and then carboxylic acids.
