Webb. Two different ketones with alpha-hydrogens are able to form a single aldol condensation product. c. Any aldehyde and ketone mixed together can react to form a single condensation product. d. Any pair of aldehyde or ketone reactants where one of the reactants has no alpha-hydrogens will lead to a single aldol product. WebDue to different active groups, aldehyde and ketone indicate different reactions for same reagent. But sometimes they show same changes (like colour changes) to some reagents. The best way to identify aldehyde from ketone is checking the oxidizing of aldehyde or ketone compound. Observe the colour change which is related to the aldehyde compound. chennai to chengannur trains

WebAldehydes and ketones react with two moles of an alcohol to give 1,1-geminal diethers more commonly known as acetals. The term "acetal" used to be restricted to systems derived from aldehydes and the term "ketal" applied to those from ketones, but chemists now use acetal to describe both. Acetals are biologically important due to their role in ... Weba number of general reactions. In an aldehyde one of the bonds on the carbonyl carbon is to a hydrogen atom, whereas in ketones, both other atoms that are attached to the carbonyl carbon are carbons. Because the carbonyl group is present in both aldehydes and ketones, the two classes often react similarly.
