In case of substituted aniline
WebIn case of aniline due to conjugation the lone pair density is less than that of methylamine. Due to this reason, aniline is less basic than methylamine. Why aniline is basic while Acetanilide is not? Basicity is the ability of a compound to donate lone pair. The lone pair in both aniline and acetanilide are delocalized due to resonance.

WebPreviously, the bile salt analog CaPA (an aniline-substituted cholic acid) was shown to block spore germination and protect rodents from CDI caused by multiple C. difficile strains and isolates. In this study, we found that CaPA is an alternative substrate inhibitor of C. difficile spore germination. By competing with taurocholate for binding ... WebElectrophilic substitution reaction. The replacement of an atom or group of atoms through an electrophile is known as an electrophilic substitution reaction. For example, …
WebBecause of their high nucleophilic reactivity, aniline and phenol undergo substitution reactions with iodine, a halogen that is normally unreactive with benzene derivatives. The mixed halogen iodine chloride (ICl) provides a more electrophilic iodine moiety, and is effective in iodinating aromatic rings having less powerful activating substituents. WebMay 24, 2024 · 3. In case of nitration in aniline, the Nitric Acid protonates the aniline to form the Anilinium ion. Now since the nitrogen atom has no lone pair to conjugate, it has no …
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 … 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:
