Chapter 5 Carboxylic Acids and Esters
Aromatic carboxylic acids (i e with a CO2H directly connected to a benzene ring) are named after the parent compound benzoic acid C OH O Benzoic acid |
Aromatic carboxylic acid preparation is possible through the oxidation of alkylbenzenes.
Vigorous oxidation of alkyl benzene compound with acidic or alkaline potassium permanganate or chromic acid can lead to the formation of aromatic carboxylic acid compounds.
How do you determine the acidity of a carboxylic acid?
Acidity Of Carboxylic Acids.
Carboxylic acid is an organic compound containing a carboxyl group (COOH) attached to an alkyl or aryl group.
They react with metals and alkalis to generate carboxylate ions.
These reactions of carboxylic acids indicate their acidic nature.
What is the acidity of aromatic carboxylic acid?
Acidity of Aromatic Carboxylic Acid: Benzoic Acid
The carboxyl group in benzoic acid is bonded to a carbon atom with sp2 hybridization, making the group highly electronegative and electron-withdrawing.
The pka value of benzoic acid is 4.2.
Benzoic acid is more potent than acetic acid but weaker than formic acid.
What determines acidity in aromatic compounds?
Aromaticity plays a big role in determining the acidity of aromatic compounds.
Complete answer: Aromatic compounds are those which fulfils the huckel's rule.
As per huckel an aromatic compound is one which contains $\\left( 4n+2 \\right)\\pi $ electrons in the ring.
