carboxylic acid pka

PDF	Carboxylic Acids E g ethanoic acid has pKa = 4 74 (alcohols have pKa ~ 16 so carboxylic acids are about 1011 times more acidic than alcohols) The reason why carboxylic acids

PDF	Acidity of Carboxylic Acids A strong acid has a low value of pKa whereas a higher value of pKa indicates that the acid is weak Value of pKa for Formic acid is 3 77 for Acetic acid it is

What is the K value of carboxylic acid?
A total of 101 pK_a values for 90 carboxylic acids, 56 pK_a values for both alcohols and phenols, and 51 pK_a values for amines, which span over 16 orders of magnitude of experimental pK_a (from −0.26 to 16.10) data, have been estimated in the aqueous condition._{15 jan. 2012}
Which carboxylic acid has highest pKa value?
Electron withdrawing group like −Cl increases the acidity of carboxylic acid and pKa value of trichloroacetic acid is very low so, it is the strongest acid.
We can see that acetic acid is the weakest acid and has the highest pKa value.
Why does carboxylic acid have a pKa of 5?
This is from my textbook: Carboxylic acids owe their acidity (pKa of about 5) to the resonance-stabilized carboxylate anions formed by deprotonation.

Carboxylic acids have pKa's of about 5 but this can be lowered considerably by electron withdrawing substituents. Here the equilibrium is very unfavorable. As we know, the reaction proceeds in the direction of converting the stronger acid into the weaker acid.
