Ketone An organic compound containing a carbonyl group bonded to two carbon atoms. Acetone is a simple ketone commonly used as a solvent. 9 Carbonyl A central feature in several classes of organic compounds. Compounds like aldehydes and ketones all contain a carbonyl group. 5 Ketone A class of...
•carbonyl groups consists of a carbon-oxygen double bond •the bond is polar due to the difference in electronegativity •aldehydes / ketones differ in what is attached to the carbon ALDEHYDES - at least one H attached to the carbonyl group HCHO or CH 3CHO C 6H 5CHO KETONES...
A ketone is an acyl group. The fourth bond on the carbon in the acyl group can be any compound, including another R group. And a ketone has two R groups attached to the carbonyl carbon. What is an acyl group in chemistry? An acyl group is any compound that has the general formula ...
(Lewis acid) and the oxygen atom is able to react with nucleophile (Lewis base) (Fig.1). Other similar reaction about carbonyl group are basically based on this principle of charge deviation. Carbonyl compound is a very broad concept, containing many derivatives such as ketone, aldehyde, acid...
The aldol reaction is very useful in synthesis. Whenever the target molecule contains either a β-hydroxy aldehyde/ketone or a conjugated enone functional group, it might come from an aldol reaction. TheClaisen Condensationis a carbonyl condensation that occurs between two ester components and gives...
Carbonyl-carbonyl n→π* interactions where a lone pair (n) of the oxygen atom of a carbonyl group is delocalized over the π* orbital of a nearby carbonyl group have attracted a lot of attention in recent years due to their ability to affect the 3D stru

carbonyl groupketonenucleophilic additionSummary Nucleophilic addition is a typical reaction of all carbonyl groups because of the polarisation of the C–O bond caused by the difference in electronegativity of the carbon and oxygen atoms. Unlike aldehydes and ketones, in the acyl derivatives, X is a...
The only difference observed was the hydroxyl group of 20β-DHF at position 20 representing a hydrogen bond donor instead of the carbonyl group of cortisol at the same position serving as hydrogen bond acceptor. Human epithelial A549 cells expressing endogenous GR and SF9 and HEK293 cells ...
