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… WebNext, we can find the pH of our solution at 25 degrees Celsius. So pH is equal to the negative log of the concentration of hydronium ions. So that's the negative log of 1.9 times 10 to the negative third, which is equal to 2.72. We also need to calculate the percent ionization. talmadge whitehead
