How do ketones and aldehydes differ
WebTests to differentiate between aldehydes and ketones 1. Tollen's Test: Aldehydes give positive Tollen's test (silver mirror) while ketones do not give any reaction. 2. Fehling's test: Aliphatic aldehydes on treatment with Fehling's solution give a reddish brown precipitate (positive result) while aromatic aldehydes and ketones do not. 3. WebIn a ketone, now not only does the oxygen gain electron density from from the carbonyl carbon, it also gains some from the alkyl groups alpha to it. Because of this small addition of electron density, ketones have slightly higher dipole moments as compared to aldehydes with similar molecular weights and thus higher boiling points. Hope that helps.

WebIntroduction: The organic molecules aldehydes and ketones include the carbonyl functional group or C=O. This group's carbon atom has two vacant bonds that can be filled using hydrogen, alkyl, or aryl substituents. Though at minimum, one of the preceding substituents is hydrogen, the chemical is an aldehyde.
