Does 3 hydroxybenzoic acid have intramolecular hydrogen bonds?
The energetics of the phenolic O-H bond in the three hydroxybenzoic acid isomers and of the intramolecular hydrogen O-H- – -O-C bond in 2-hydroxybenzoic acid, 2-OHBA, were investigated by using a combination of experimental and theoretical methods.

How do you make a 4-hydroxybenzoic acid?
4-Hydroxybenzoic acid is produced commercially from potassium phenoxide and carbon dioxide in the Kolbe-Schmitt reaction. It can also be produced in the laboratory by heating potassium salicylate with potassium carbonate to 240 °C, followed by treating with acid.
What is the density of 4-hydroxybenzoic acid?

4-Hydroxybenzoic acid/Density
Why is auto hydroxybenzoic acid more acidic than para hydroxybenzoic acid?
The intramolecular hydrogen bond in ortho-hydroxybenzoic acid between the COO− and the -OH groups forms a six membered ring. Since this structure is very stable, the deprotonation of the acid is favoured and the compound is more acidic.
Which is more acidic Ortho hydroxybenzoic acid or para hydroxybenzoic acid?
so to answer your question, ortho hydroxy benzoic acid is more acidic because in the ortho isomer, strong hydrogen bridge will be formed between the phenolic -OH- and the carboxylate ion and this will tend to stabilize the conjugate crboxylate base hence increasing the acidity.

How many carbon atoms are in hydroxybenzoic acid?
SMILES (Simplified Molecular-Input Line-Entry System) string of 4-HYDROXYBENZOIC ACID. The SMILES string of 4-HYDROXYBENZOIC ACID is OC(=O)c1ccc(O)cc1, which can be can be imported by most molecule editors for conversion back into two-dimensional drawings or three-dimensional models of the 4-HYDROXYBENZOIC ACID.
Which is more acid para hydroxybenzoic acid?
So, meta-hydroxybenzoic acid is more acidic than para-hydroxybenzoic acid. Note: The acid-weakening effect of the electron-donating group and acid-strengthening effect of the electron-withdrawing group is more pronounced at the para than at meta position of the benzoic acid.
Why does 4 hydroxybenzoic acid have a higher melting point than salicylic acid?
Intermolecular Hydrogen Bonds in 4-hydroxybenzoic acid Therefore both groups can be used for hydrogen bonds between molecules. This results in more extensive hydrogen bonds and higher melting point for 4-hydroxybenzoic acid.
