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. The amin… WebFeb 22, 2024 · The pH of the solution of aniline is; pH = 4.64. pH of aniline solution. According to the question; We are required to determine the hydrogen ion concentration, pH of the given aniline solution. Since, the given Kb is kb = 4. 3 × 10⁻¹⁰. Hence, it follows that; Ka = 10-¹⁴/4. 3 × 10⁻¹⁰. Ka = 2.3 × 10⁻⁵.
