Some chemists prefer to use the short hand notation of H + rather than H 3O + t o represent the proton exchanged during the …
WebPhenols are weakly acidic (pKa = 10) because of their resonance stabilized conjugate base, phenoxide. Alcohols are considered neutral with pKa values similar to water (pKa = 14). … Web3. Carboxylic acid pKa = 4‐5 4. Ammonium ion pKa = 9‐10 5. Phenol pKa = 10 6. Thiol pKa = 10 7. Alcohol pKa = 16‐18 8. Water pKa = 15.7 9. Amide pKa = 18 10. Alpha …
Web14 Aug 2024 · pKb = 14.00 − 4.83 = 9.17. Because pKb = − logKb, Kb is 10 − 9.17 = 6.8 × 10 − 10. In this case, we are given Kb for a base (dimethylamine) and asked to calculate Ka … WebThe pKa measures how tightly a proton is held by a Bronsted acid. A pKa may be a small, negative number, such as -3 or -5. It may be a larger, positive number, such as 30 or 50. …
Web29 Jan 2016 · Explanation: As physical scientists we should seek out numerical data: H 3C − CO2H ; pKa = 4.76 ClH 2C −CO2H ;pKa = 2.86 Cl2H C − CO2H ;pKa = 1.35 Cl3C − CO2H ; pKa = 0.66 So of course, we have to rationalize the enhanced acidity of the halogenated acids. This is a very old problem in inorganic chemistry.
