Table D.2 Dissociation Constants for Bases at 25 °C Name Kb Ammonia 1.8 x 10-5 Methylamine Ethylamine Dimethylamine Trimethylamine Formula NH, CH3NH₂ C,HẠNH, (CH;),NH (CH3)3N 4.4 X 104 6.4 X 104 5.4 X 104 6.4 x 10-5 Which of the following are true from the table of base dissociation constants? Select the correct response(s): Electron-donating groups make the lone pair of nitrogen more available for donation. Steric factors do not affect the basicity of the amine. The more electron-donating groups the more basic is the amine. Electron-donating groups make the lone pair of nitrogen less available for donation.. The availability of the lone pair of nitrogen is decreased by steric factors. The smaller the Kb the more available the lone pair of nitrogen. The larger the Kb the more available the lone pair of nitrogen.
