Greetings,
This post will explain Benzoic Acid; The simplest aromatic acid. Benzoic acid is simply a benzene ring bonded to a carboxyl functional group. One could also say that a carboxyl group has been added to a benzene ring.
The expanded formula of Benzoic Acid is C6H5COOH. The acidic hydrogen is on the right side of the formula. Benzoic acid is also the simplest aromatic carboxylic acid. The following graphic depicts the structure and water-ionization of benzoic acid.
A ball-and-stick model cannot show the resonance around the benzene ring, so that is its drawback. The ionization structures are condensed. With condensed Lewis structures, a corner is understood to be a carbon atom. The number of hydrogen atoms on each carbon is determined from the four-electron valance of carbon (In other words, carbon forms four bonds). The benzene ring itself provides three bonds for each carbon atom, so there is only room for one additional atom on each carbon - five hydrogens plus the carbon of the carboxyl group.
That's all for now and sorry to have been away for so long!
As always, thank you for reading!
