acidity of carboxylic acids with halogens
The acidic strength of hydrogen halide increases in the order of HF< HCl< HBr< HI.
What factors affect the acidity of carboxylic acids?
The presence of such groups near the COOH group of a carboxylic acid often has an effect on the acidity.
In general, electron-withdrawing groups increase acidity by increasing the stability of the carboxylate ion.
In contrast, electron-donating groups decrease acidity by destabilizing the carboxylate ion.
What is the effect of CL on the acidity of carboxylic acids?
C: Inductive effects
The presence of the chlorine atoms clearly increases the acidity of the carboxylic acid group, but the argument here does not have to do with resonance delocalization, because no additional resonance contributors can be drawn for the chlorinated molecules.
Do carboxylic acids react with halogens?
The silver(I) salts of carboxylic acids react with halogens to give unstable intermediates which readily decarboxylate thermally to yield alkyl halides.
The reaction is believed to involve homolysis of the C-C bond and a radical chain mechanism.
