Sulfonic acid | Uses, Structure & Synthesis | Britannica
WEBSulfonic 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 - Wikipedia
WEBIn 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.
Sulfonic Acid - Chemistry LibreTexts
WEBFeb 28, 2022 · 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).
19.12 Sulfonic Acids - Chemistry LibreTexts
WEBSulfonic 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.
SO3H (Sulfonic acid) - Preparation, Chemical Reactions
WEBA sulfonic acid is sulfuric acid with an organic substituent in place of one of the hydroxyl groups. The parent sulfonic acid, HS(=O) 2 (OH), a tautomer of sulphurous acid, S(=O)(OH) 2, is the parent chemical (with the organic group replaced by hydrogen).
Sulfonic Acid - an overview | ScienceDirect Topics
WEBSulfonic 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.
Sulfonic acid Definition & Meaning - Merriam-Webster
WEBApr 11, 2024 · The meaning of SULFONIC ACID is any of numerous acids that contain the SO3H group and may be derived from sulfuric acid by replacement of a hydroxyl group by either an inorganic anion or a monovalent organic group.
17.3: The Sulfonic Acid Group and its Derivative
WEBApr 26, 2020 · Sulfonic acids are organic analogs of sulfuric acid, an inorganic compound that is a very strong acid. Like sulfuric acid, sulfonic acids are highly corrosive, they react vigorously with water, and can cause skin burns.
Sulfonic Acid - an overview | ScienceDirect Topics
WEBOperating conditions usually involve 24 water molecules for each sulfonic acid group. The use of polystyrene that has been subsequently sulfonated is an excellent technique for raising the number of sulfonic acid groups in the membrane, as well as increasing its hydrophilicity and conductivity [4].
