WebJan 23, 2024 · Phenylamine is slightly soluble in water - about 3.6 g (depending on where you get the data from!) of phenylamine will dissolve in 100 g of water at 20°C. Mixtures containing more phenylamine than this separate into two layers, with the phenylamine forming the bottom one. WebThe effect of this is that the pH of a solution of phenylamine will be quite a bit lower than a solution of ammonia or one of the aliphatic amines of the same concentration. For … 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. The amine in anilines is a slightly pyramidalized molecule, with hybridization of the nitrogen somewhere between sp and sp . The nitrogen is described as having high p character.
