WebIn the first case, the electron density on the N atom is (slightly) reduced and thus the basicity of o-toluidine. In the latter case, a similar interaction provides additional stabilisation of the carboxylate. As a result, o-toluic acid is more acidic than the isomers. Solution 2: WebAniline refers to the formation of Acetanilide by nucleophilic replacement reaction with acetic anhydride and the reaction is called acetylation. Aniline serves as the nucleophile in this reaction and acetic anhydride group acyl …
WebWhat about the basicity of substituted anilines? Whether a substituted aniline is more or less basic than aniline, depends on the nature of the substituent. Electron-donating groups increase the electron density of the benzene ring, making the …
