What is the structure of sulphonic acid?
A 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. As a substituent, it is known as a sulfo group.
How is benzene sulphonic acid prepared?
The benzene-sulphonic acid can be obtained by reacting with oleum from benzene. The benzenesulfonic acid thus formed is treated at high temperatures with molten sodium hydroxide which leads to sodium phenoxide formation. Finally, phenols are supplied by the sodium phenoxide on acidification.
What is C6H5SO3H?
This acid is an organosulfur compound with the formula C6H5SO3H. It is the simplest aromatic sulfonic acid. It forms colourless deliquescent sheet crystals or a white waxy solid that is soluble in water and ethanol, slightly soluble in benzene and insoluble in carbon disulfide and diethyl ether.
What is benzene nitration?
The nitration of benzene Nitration happens when one (or more) of the hydrogen atoms on the benzene ring is replaced by a nitro group, NO2. Benzene is treated with a mixture of concentrated nitric acid and concentrated sulfuric acid at a temperature not exceeding 50°C.
What is the formula of acid anhydride?
Acid anhydrides contain two acyl groups and have the general formula RC(=O)OC(=O)R or acyl—O—acyl. The acyl groups may be the same (symmetric) or different (asymmetric or mixed). The simplest and most common acid anhydrides are symmetrical derivatives of monobasic acids.
Is sulfonic acid a strong acid?
Sulfonic acids are similar to carboxylic acids and have the general structure of RSO3H. Sulfonic acids are very strong acids (pKa ~ -7). The conjugate bases of sulfonic acids are called sulfonate anions and are resonance stabilized.
What is benzene sulphonic acid used for?
Uses. Salts of Benzenesulfonic acid such as Sodium benzenesulfonate (Ludigol) and Monoethanolamine benzenesulfonate are used as surfactants in laundry detergent. A variety of pharmaceutical drugs are prepared as benzenesulfonate salts and are known as besilates (INN) or besylates (USAN).
How do you prepare phenol from benzene?
In this method, benzene sulfonic acid is reacted with aqueous sodium hydroxide. The resulting salt is mixed with solid sodium hydroxide and reacted at a high temperature. The product of this reaction is sodium phenoxide, which is acidified with aqueous acid to make phenol.
Which is least reactive in electrophilic substitution?
benzene
Electrophilic aromatic substitution (EAS) is where benzene acts as a nucleophile to replace a substituent with a new electrophile. That is, benzene needs to donate electrons from inside the ring. So, benzene becomes less reactive in EAS when deactivating groups are present on it.
