In case of substituted aniline
WebAt room temperature, aniline, the simplest aromatic amine, is a clear to slightly yellow, oily liquid that darkens to a brown color on exposure to air. It has a low vapor pressure at room temperature. Aniline is slightly soluble in water and is miscible with most organic solvents. Synonyms include aminobenzene, aminophen, arylamine, benzenamine, aniline oil, and … 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 …
