Inductive effect of alkyl group in gas phase
WebInductive effect of alkyl groups activates the direction of the ortho or para substitution, which is when s electrons gets pushed toward the ring. Deactivating group (meta directors) The deactivating groups deactivate the ring by the inductive effect in the presence of an electronegative atom that withdraws the electrons away from the ring. 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 ...
