  1. 27 de oct. de 2017 · Bordwell pKa Table. General Info. pKa is an acid dissociation constant used to describe the acidity of a particular molecule. Its value is directly related to the structure of the given compound.

  3. The pka of water and H 3O+ have been experimentally determined to be 14.0 and 0.0, respectively. Earlier values of 15.7 and –1.74, respectively are erroneous numbers proposed by scientists who made some errors in the calculated “rational” values. See: 1) Helv. Chim. Acta 2014, 97, 1. and 2) J. Chem. Educ. 2017, 94, 690.

  4. Find the pka values of amines, quinolines, benzacridines, caffeine, cocaine, and other organic compounds in this table. The pka values are measured in different solvents and at different temperatures, and are referenced to the original sources.

  5. D.H. Ripin, D.A. Evans *Values <0 for H2O and DMSO, and values >14 for water and >35 for DMSO were extrapolated using various methods. 38 (12) (estimate) pKa's of Nitrogen Acids H2O (DMSO) Chem 206 Substrate Substrate Substrate pKa Substrate DABCO DBU Et3N +H i-Pr2N +H 2 i-Pr2NH EtN+H 3 TMS2NH N+H 4 NH3 TMP (41) (36 THF))

  6. - [Voiceover] Let's look at how to use a pKa table. Remember from general chemistry that pKa is equal to the negative log of the Ka. And the lower the pKa value the stronger the acid. pka values are used a lot in organic chemistry, so it's really important to become familiar with them.
