WebJun 1, 2024 · Answer. Gaurav Pathak. Tutor. 07/01/2024. (a) Tollen's test: Propanal is an aldehyde. Thus, it reduces Tollen's reagent. But, propanone being a ketone does not reduce Tollen's reagent. (b) Fehling's test: Aldehydes respond to Fehling's test, but ketones do not. Propanal being an aldehyde reduces Fehling's solution to a red-brown … WebThe ethanal has been oxidised by the Fehling's reagent. As a result, the Cu⁺² ions (blue) in the Fehling's reagent were reduced to Cu⁺ ions (red) by the ethanal. What happens when the experiment is repeated with propanone and why? no colour change occurs as ketones cannot be further oxidised by Fehling's reagent.
