Is benzenesulfonic acid strong?

It is a strong acid, being almost fully dissociated in water. Benzenesulfonic acid and related compounds undergo desulfonation when heated in water near 200 °C.

Which acid is weaker than benzoic acid?

The acidity is due to the stablity of congugate base. Here, In Formic acid resonance is stabilised via two equivalent resonating structure. On the other hand, in case of Benzoic acid the conjugate base is stabilised via resonance of benzene ring.

Why is benzenesulfonic acid a strong acid?

Benzene sulphonic acid donates its proton and forms benzene sulfonate ion as a conjugate base. In this case, benzene sulfonate ion is more stable than benzoate ion as it shows more number of resonance structures than the benzoate ion. Thus benzene sulphonic acid is the stronger acid than benzoic acid.

What is benzenesulfonic acid used for?

Benzenesulfonic acid is used as an acid catalyst. The sodium salt is used to standardize dyes. A variety of pharmaceutical drugs are prepared as benzenesulfonate salts and are known as besilates (INN) or besylates (USAN).

Why is benzoic acid a stronger acid than acetic acid?

Benzoic acid itself is a somewhat stronger acid than acetic acid. The carboxyl group of benzoic acid is attached to an sp2-hybridized carbon which is more electronegative and electron-withdrawing than the sp3-hybridized carbon attached to acetic acid.

Which is more acidic cyclohexanecarboxylic acid or benzoic acid?

The acidic strength of benzoic acid is stronger than cyclohexane carboxylic acid and the reason behind is of electronegative nature influenced by hybridization where sp. This can be verified with pKa values where for benzoic acid is 4.2 while in cyclohexane carboxylic acid is 4.9 hence the answer aligns to benzoic acid …

Why is benzoic acid strong?

Which is more acidic oxalic acid or benzoic acid?

Oxalic acid is more acidic. To understand this we just have to compare relative stability of conjugate base that will be formed after abstraction of proton. Required knowledge- Benzoic acid is more acidic than every aliphatic Carboxylic acid but formic acid is more acidic than benzoic acid.

Which of the following is weaker acid?

Acetic acid is a weak acid whereas HCl is a strong acid.

Which one is the weakest acid among the following?

HF is the weakest acid as it does not give proton easily.
