Which one is most, and least polar among acetic acid, salicylic acid, and acetylsalicylic acid? I googled a lot, and they said salicylic acid is more polar than acetylsalicylic acid because of the -OH group, and acetic acid is more polar than salicylic acid because salicylic acid has benzene ring. So it says acetic>salicylic>acetylsalicylic. But my another research says dipole moments of them are 1.74D, 2.65D, and 6.49D, and I know bigger dipole moments, more polar. So it says acetic
