The base strength in amines is influenced by the electron-donating or withdrawing effects of substituents. In this case, the presence of an electron-donating group (CH3-) increases the base strength, while the presence of an electron-withdrawing group (Br-) decreases it. Therefore, the amine with the electron-donating group (CH3-) is the strongest base, followed by the amine with the hydrogen (indicating no additional electron-donating or withdrawing effect), and finally, the amine with the electron-withdrawing group (Br-) is the weakest base.
