Solution
Among dimethylamine (pKb = 3.27) and diethylamine (pKb = 3.0), diethylamine is more basic. The basicity of amines is quantitatively expressed by their pKb values, with a smaller pKb value indicating a stronger base. Therefore, since diethylamine has a lower pKb value compared to dimethylamine, it is the more basic compound.
