WebJan 2, 2024 · Amide group in acetanilide is donating group to benzene, and the amide group in N-methylbenzamide is electron withdrawing group. In acetanilide, the benzene bonded with the nitrogen atom (amide group) that make this substituent role as donating group. The lone pair electron from nitrogen atom was donated to benzene and increased the …

Inductive Effects of Alkyl Groups - Chemistry LibreTexts
WebIn short, the groups that donate electron density to the ring and make it electron-rich are activators. The ones that withdraw the electron density are deactivators. Activators increase the rate of electrophilic aromatic substitution and deactivators decrease it: There are two factors that determine if the group is electron donating or withdrawing. Because of the full or partial positive charge on the element directly attached to the ring for each of these groups, they all have a moderate to strong electron-withdrawing inductive effect (known as the -I effect). They also exhibit electron-withdrawing resonance effects, (known as the -M effect): Thus, these groups make the aromatic ring very electron-poor (δ+) relative to b… Web2. Alkyl substituents ( e.g. -CH 3, -CH 2 CH 3) are also electron donating groups - they activate the aromatic ring by increasing the electron density on the ring through an … thomas o\u0027reilly obituary
