| Abstract: | The ionization constants of 2-hydroxyanilinium,
2-methoxyanilinium, 4-nitroanilinium ions, N-(2′-hydroxyphenyl)-phthalamic acid and N-(2′-methoxyphenyl) phthalamic acid, determined spectrophotometrically, have been rationalized in terms of internal hydrogen bonding and steric
hindrance between o–substituent and reaction site. |
