Benzenesulfonic Acid

Benzoic Acid

Benzyl Alcohol

Benzylamine

P-Cresol

P-Toluidine
Acid/Base| Structure| pH| Why It is a strong/weak acid/base| Benzenesulfonic Acid| | 1| This is a strong acid because it has a pH of 1. Another reason why this is a strong acid is that its conjugate base has strong resonance stabilization.| Benzoic Acid| | 3| This is a strong acid because it has a pH of 3. Another reason is that benzoic acid has a conjugate base with strong resonance stabilization. Benzenesulfonic acid has more resonance stabilization and this is why it is a stronger acid than benzoic acid.| Benzyl Alcohol| | 6| Benzyl Alcohol is neutral. We know this because benzyl has a pH of 6. This is neutral because in 50% ethanol, a neutral solution does not have a pH of 7. Also Benzyl Alcohol’s conjugate base has little resonance stabilization. This indicates that it is weak. | Benzylamine| | 10| Benzylamine is a weak base. This is true because it has a pH of 10. Another clue is that its conjugate acid has little resonance stabilization.| P-Cresol| | 6| P-Cresol is a neutral compound. This is true because it has a pH of 6. Also, its conjugate base has little resonance stabilization. This indicates that it is weak.| P-Toluidine| | 7| P-Toluidine is a weak base. This is true because it has a pH of 7. This is also true because p-toluidine’s conjugate acid has little resonance stabilization. |
