Aryl-N distances In aniline, the C−N bond length is 1.41 Å, compared to 1.47 Å for cyclohexylamine, indicating partial π-bonding between N and C. The C(aryl)-NH2 distance in anilines is highly sensitive to substituent effects. This distance is 1.34 Å in 2,4,6-trinitroaniline vs 1.44 Å in 3-methylaniline. … Visa mer Aniline (from Portuguese anil 'indigo shrub', and -ine indicating a derived substance) is an organic compound with the formula C6H5NH2. Consisting of a phenyl group (−C6H5) attached to an amino group (−NH2), aniline is the … Visa mer The chemistry of aniline is rich because the compound has been cheaply available for many years. Below are some classes of its reactions. Oxidation Visa mer Aniline was first isolated in 1826 by Otto Unverdorben by destructive distillation of indigo. He called it Crystallin. In 1834, Friedlieb Runge isolated a substance from coal tar that turned a beautiful blue color when treated with chloride of lime.
