In salicylic acid the hydrogen atom in OH group have a tendency to form hydrogen bonding with oxygen atom in the COO - group thus leaving the H+ ion freely available.
In case of ortho methoxy benzoic acid, the possibility of hydrogen bonding is avoided by the presence of strong -CH3 group.
Hence salicylic acid is stronger than ortho methoxy benzoic acid.

Why ortho chlorobenzoic acid is stronger than benzoic acid?
Ortho chlorobenzoic acid is stronger than benzoic acid due to the electron-withdrawing effect of the chlorine atom. This increases the acidity of ortho chlorobenzoic acid by stabilizing the conjugate base through delocalization of the negative charge. In contrast, benzoic acid has no such electron-withdrawing substituent.
Why benzoic acid is stronger than ethanoic acid?
Benzoic acid is stronger than ethanoic acid because the benzene ring in benzoic acid stabilizes the conjugate base when the acidic hydrogen is removed, making it less likely to donate a proton. In contrast, ethanoic acid lacks this stabilizing effect, making it easier to donate a proton, thus making it a weaker acid.
Why o-hydroxy benzoic acid is strong than m-hydroxy benzoic acid?
o-Hydroxybenzoic acid is stronger than m-hydroxybenzoic acid because the hydroxyl group in o-hydroxybenzoic acid is in closer proximity to the carboxylic acid group, allowing for stronger intramolecular hydrogen bonding. This results in greater stabilization of the molecule and higher acidity.
Why benzoic acid is stronger acid than ethanoic acid?
Benzoic acid is stronger than ethanoic acid due to the presence of a more stable conjugate base after losing a proton. The conjugate base of benzoic acid (benzoate ion) is stabilized by resonance delocalization of the negative charge across the benzene ring, making it less likely to reaccept a proton. In contrast, the conjugate base of ethanoic acid (acetate ion) is not as stabilized, leading to a greater tendency to reaccept a proton.
Why is methanoic acid more acidic than benzoic acid?
We would certainly expect benzoic acid to be more acidic than methanoic acid, due to stabilisation of the benzoate anion caused by the delocalisation of the electrons on the oxygen atom over the benzene ring. However, in practice, it is found that methanoic acid is actually more acidic than benzoic acid(has a greater Ka value). This is because methanoic acid is more soluble in water than benzoic acid, so there is greater ionisation of methanoic acid in water than benzoic acid.

Is benzoic acid a stronger acid than HCl?
No, benzoic acid is not soluble in hydrochloric acid. However if you boil the benzoic acid to where it is water soluable and add hydrochloric acid it forms it back into the solid
What is the derivative of benzoic acid?
The derivative of benzoic acid is sodium benzoate, which is often used as a preservative in food and beverages due to its antimicrobial properties. Sodium benzoate is the sodium salt of benzoic acid and is more soluble in water than benzoic acid itself.
Why is methanoic acid more acidic than benzoic acid?

A mixture of camphor and benzoic acid can be easily separated by?
Benzoic acid is more soluble than camphor in ethanol. The solution can be filtrated.
Which is more acidic benzoic acid or acetic acid?
Benzoic acid is the stronger acid compared to ethanoic acid. However, ethanoic acid is more corrosive and will burn skin etc more than benzoic acid. Corrosivity/burn potential are not the same as acid strength. This is due to the delocalisation of the lone pair of electrons on the oxygen atom into the benzene, increasing the polarity of the -OH bond and thus makes the cleaving of the H+ ion easier. The delocalisation of electrons into the benzene ring also stabilises the carboxylate ion. Therefore the position of equilibrium lies more to the right and this shows that benzoic is a more acidic acid. The simplified version is that a benzene ring is electron withdrawing and a methyl group is electron releasing. The electron withdrawing power makes the releasing of the H+ ion easier.
Which is more acidic formic acid or benzoic acid?
Formic acid is more acidic than benzoic acid. This is because formic acid has a simpler molecular structure with a hydrogen atom attached to a carboxyl group, making it easier to release the acidic hydrogen ion compared to benzoic acid, which has a more complex aromatic ring structure.
Why 4 hydroxy benzoic acid is less acidic than 2 hydroxy benzoic acid?
as because in 2-hydroxy benzoic acid, there is a possibility of H-bonding which makes the dissociated ion stable and will not combine with H+ ion leaving it free, while it is not so in case of 4-hydroxy benzoic acid.
How do you separate benzoic acid from a mixture of napthalene and benzoic acid?
One way to separate benzoic acid from a mixture of naphthalene and benzoic acid is by sublimation. Naphthalene sublimes at a lower temperature compared to benzoic acid, allowing for the separation of the two compounds based on their difference in sublimation temperatures. By heating the mixture and collecting the sublimate, one can isolate benzoic acid from naphthalene.
