Sulfonic acid - Wikipedia
In organic chemistry, sulfonic acid (or sulphonic acid) refers to a member of the class of organosulfur compounds with the general formula R−S(=O) 2 −OH, where R is an organic alkyl or aryl group and the S(=O) 2 (OH) group a sulfonyl hydroxide. [1]
Sulfonic acid | Uses, Structure & Synthesis | Britannica
Sulfonic acid, any of a class of organic acids containing sulfur and having the general formula RSO3H, in which R is an organic combining group. The sulfonic acids are among the most important of the organosulfur compounds; the free acids are widely used as catalysts in organic syntheses, while the
Sulfonic Acid - an overview | ScienceDirect Topics
Sulfonic acid are organosulfur compounds containing a S(O) 2 OH functional group (sulfonyl hydroxide). In 2000, Wu and co-workers [125] reported the first attempt to study a sulfonic acid, the p-toluenesulfonic acid, by solid-state 17 O NMR. About a decade later, Wu and his teams published two more studies on sulfonic acids.
SO3H (Sulfonic acid) - Preparation, Chemical Reactions
Sulfonic acid is an extremely powerful organic acid with an acidity similar to that of inorganic acids. A sulfonic acid is sulfuric acid with an organic substituent in place of one of the hydroxyl groups.
Sulfonic Acid - Chemistry LibreTexts
2022年2月28日 · A sulfonic acid is an oxoacid that has the following general structural formula. In the most common sulfonic acids, R is either an alkyl group (alkanesulfonic acid) or an aryl group (arenesulfonic acid).
17.4: Sulfonic Acids - Chemistry LibreTexts
Sulfonic acids are similar to carboxylic acids and have the general structure of RSO 3 H. Sulfonic acids are very strong acids (pKa ~ -7). The most common sulfonic acid is p-toluenesulfonic acid. The conjugate bases of sulfonic acids are called sulfonate anions and are resonance stabilized. Consequently, sulfonate anions make good leaving groups.

Sulfonic acid is an unstable acid with the formula H-S(=O) 2-OH. Sulfonic acid is the less stable tautomer of sulfurous acid HO-S(=O)-OH into which sulfonic acid converts rapidly. Derived compounds which replace the sulfur-bonded hydrogen with organic groups are stable.
Sulfonic acid - Wikiwand
Sulfonic acids are strong acids. They are commonly cited as being around a million times stronger than the corresponding carboxylic acid. For example, p -Toluenesulfonic acid and methanesulfonic acid have p K a values of −2.8 and −1.9, respectively, while those of benzoic acid and acetic acid are 4.20 and 4.76, respectively.
