21.4: Acidity and Basicity of Amines - Chemistry LibreTexts
2020年8月27日 · Basicity of Aniline. Aniline is substantially less basic than methylamine, as is evident by looking at the pK a values for their respective ammonium conjugate acids (remember that the lower the pKa of the conjugate acid, the weaker the base).
Nucleophilicity Trends of Amines – Master Organic Chemistry
2018年5月7日 · Since “the weaker the acid, the stronger the conjugate base”, a convenient way to compare the basicity of amines is by the pK a of the conjugate acid (which we can call pK a H). The higher the pK a H, the greater the basicity of the amine. (see: Basicity of Amines and pK a H)
23.1: Relative Basicity of Amines and Other Compounds
Basicity of aniline. Aniline is substantially less basic than methylamine, as is evident by looking at the pK a values for their respective ammonium conjugate acids (remember that the lower the pKa of the conjugate acid, the weaker the base).

pKa of Aniline - vCalc
2021年8月10日 · The pKa of Aniline constant displays the pKa of the conjugate acid for aniline (4.61). The pKa value of a compound indicates that strength of an acid. The pKa is the negative log base ten of the Ka value, also known as the acid dissociation constant. An efficient way to quantify basicity of an amine is to study the pKa of its conjugate acid.

2017年4月26日 · The the pK a H of aniline is 4.6, and pK a H of cyclohexylamine is 11.2. (The higher the pK a H, the stronger the base). The basicity is decreased even further when a second phenyl ring is attached to the nitrogen (pK a H = 0.78).
