WebAnd what we're going to do is drop the E and add "-AL" for aldehyde. So this would be "Butanal," right. So a four-carbon aldehyde is "butanal" with an "-AL"ending like that. Let's go ahead and look at some more examples. So once again we're going to number to give our carbonyl carbon the lowest number possible. WebThis study guide summarizes the key points for reactivities of aldehydes and ketones and the main addition reactions with water, alcohols, amines, and cyanides. These together with protecting groups for aldehydes and ketones, the Wittig reaction and 1,2/1,4 additions to α, β -unsaturated compounds are covered with specific examples.
Web19.5 Relative Reactivity of Aldehydes and Ketones aldehydes are more reactive toward nucleophilic addition than ketones. In general aromatic aldehydes (benzaldehydes) are less reactive because of resonance with the aromatic ring 19.6 Nucleophilic Addition of H 2O: Hydration Water can reversibly add to the carbonyl carbon of WebWhy are ketones less reactive than aldehydes? A. Ketones are more sterically hindered. B. Ketones are less electron deficient due to donation from the two alkyl groups. C. C. The statement is false; ketones are more reactive than aldehydes. D. Both A and B D If a compound is reduced, what is the result? A. Fewer C-H bonds
WebA few drops of the aldehyde or ketone are added to the reagent, and the mixture is warmed gently in a hot water bath for a few minutes. Aldehydes reduce the complexed copper (II) ion to copper (I) oxide. Because the solution is alkaline, the aldehyde itself is oxidised to a salt of the corresponding carboxylic acid.
