pka Table - 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.
table with pKa values for a bunch of organic (and inorganic) molecules Here’s your typical pKa table with pKa values for a bunch of organic (and inorganic) molecules. You can find a table like that in any organic chemistry textbook. Your instructor has probably given you one of those.
Not knowing pKa values in organic chemistry is like not knowing the value of the hands in poker. In this scheme, alkyl anions are the equivalent of the royal flush – they win the proton from everything underneath them in the table. Why is pKa so important? Because every nucleophile is ...
Using a pKatable, you can apply the Principle of Acid-Base Mediocrity and examine any random acid base reaction, once you have identified the main functional group. It’s very powerful. For example, will CH3CH2S(-), the conjugate base of ethanethiol deprotonate hydrogen gas (H2) to give ...

GuntherFischer, inAdvances in Heterocyclic Chemistry, 2013 3.4.3pKaValues Table 10lists pKavalues of several DTTs bearing acidic or basic groups. DTT 5-carboxylic acids (e.g.64) are rather strong acids, comparable to dichloroacetic acid (98J(P2)387); in the case of the less-acidic 4-carbo...
First, we will focus on individual atoms, and think about trends associated with the position of an element on the periodic table. We’ll use as our first models the simple organic compounds ethane, methylamine, and ethanol, but the concepts apply equally to more complex biomolecules with the...
Most organic chemistry textbooks conjure up the 15.7 value in an attempt to explain the comparative reactivities of methanol, ethanol, and water, but the logic used is completely incorrect. The concentration of water does not belong in the calculation. The ACTIVITY of water, as the solvent, is...
