WebSimple ketones and aldehydes are not acidic or basic in the sense that they appreciably affect the concentrations of H3O+ or OH- in water solution. Other more complicated carbonyls such as acetylacetone are weak Bronsted acids in water. Web2 jun. 2010 · Epimerization of the alpha-carbon of ketones and aldehydes can readily occur in the presence of acid and base. Carbons further down the chain are not affected since it is only the alpha carbon that is acidic. 3. How Exactly Is Keto-Enol Tautomerism Catalyzed By Acid?

Web21 jun. 2024 · In addition to water, interconversion of keto and enol tautomers is greatly assisted by the presence of acid or base. [ Note 6 ] In the presence of acid, the carbonyl oxygen is protonated (Step 1, form O-H). Then, in the slow step, the alpha-carbon is deprotonated to give the enol (Step 2, break C-H, form C-C (pi), break C-O (pi). ). Webthe chain is numbered so that the carbonyl C has the lowest possible number. Select all the structural features that determine the chemical and physical properties of aldehydes and ketones. -the carbonyl C is an electrophilic center. -the C=O group is polarized. -the C and O of the C=O group are sp2 hybridized.

"WebSo if the conjugate base is destabalized, that means that acetone is not quite as likely to donate a proton. So that's the situation when you have a ketone here. When we had an aldehyde, we didn't have this electron donating factor, and so that's just one way to think about why an acetone, why a ketone, is not as acidic as an aldehyde in general.
