    Constants ! Periodic Part A Explain why amino acids, unlike most amnines and carboxylic acids, are insoluble in diethyl ether. O An amino acid is insoluble in diethyl ether (a relatively nonpolar solvent), because an amino acid exists as a nonpolar molecule. In contrast, carboxylic acids and amines are more polar because they have a single charge depending on the extent of dissociation in diethyl ether An amino acid is insoluble in diethyl ether (a relatively nonpolar solvent), because an...
