Alkyl Group Definition, Characteristics & Nomenclature

WebWhen the carbonyl group is linked to one alkyl or aryl group and one hydrogen atom, the resulting carbonyl compound is called an aldehyde. The general formula of an aldehyde is R-CHO. Ketones are carbonyl compounds in which the carbonyl carbon is linked to two alkyl or aryl groups. Their chemical formulae can be generalized to R-(C=O)-R’. WebSince an sp 3 carbon is less electronegative than an sp 2 carbon, a methyl or similar sp 3 alkyl (R) group can act as a σ-donor, putting some extra electron density into the ring, giving a +I effect (activating). Groups based on more electronegative atoms (O, F, Cl) may be σ-acceptors, drawing electron density away from the ring via a simple ... fidelity virginia beach vaWebFigure 2.

WebThe other alkyl groups have "electron-pushing" effects very similar to the methyl group, and so the strengths of the other aliphatic primary amines are very similar to methylamine. Note: If you want more information about the inductive effect of alkyl groups, you could read about carbocations (carbonium ions) in the mechanism section of this site. WebSince the bond between the carbon and the leaving group is being broken in the transition state, the weaker this bond is the lower the activation energy and the faster the reaction. This leads to the following reactivity order for alkyl halides. Practically, alkyl fluorides are not used for S N 2 reactions because the C-F bond is too strong ...
