Q1. A chemist needs to distinguish between a sample of propanal and propanone in an industrial quality control lab. Which reagent will show a positive result only for propanal?
Answer: Tollen's reagent
Explanation: Tollen's reagent oxidizes aldehydes like propanal but fails to react with ketones like propanone due to lack of an oxidizable hydrogen.
