Q1. A student finds an unlabeled bottle containing either an aldehyde or a ketone. Which reagent will confirm the presence of a carbonyl group regardless of its specific type?
Answer: 2,4-Dinitrophenylhydrazine
Explanation: 2,4-DNPH reacts with both aldehydes and ketones to form yellow/orange precipitates; Tollen's reagent only reacts with aldehydes, not ketones.
