WebJul 5, 2024 · Thiols. Thiols are often called “mercaptans,” a reference to the Latin term mercurium captans (capturing mercury), since the -SH group forms strong bonds with mercury and its ions. Thiols are analogous to alcohols. Thiols are weakly acidic (pK a ~ 10) and are much stronger acids than alcohols (pKa ~ 16). WebChimie organique II TD N°2; Other related documents.

Thiols are the sulfur analogue of alcohols (that is, sulfur takes the place of oxygen in the hydroxyl ( −OH) group of an alcohol), and the word is a blend of " thio- " with "alcohol". Many thiols have strong odors resembling that of garlic or rotten eggs. Thiols are used as odorants to assist in the detection of natural … See more In organic chemistry, a thiol , or thiol derivative, is any organosulfur compound of the form R−SH, where R represents an alkyl or other organic substituent. The −SH functional group itself is referred to as either a thiol group … See more Thiols having the structure R−SH, in which an alkyl group (R) is attached to a sulfhydryl group (SH), are referred to as alkanethiols or alkyl thiols. Thiols and alcohols have similar connectivity. Because sulfur atoms are larger than oxygen atoms, C−S bond lengths – … See more Odor Many thiols have strong odors resembling that of garlic. The odors of thiols, particularly those of low molecular weight, are often strong and … See more In industry, methanethiol is prepared by the reaction of hydrogen sulfide with methanol. This method is employed for the industrial synthesis of methanethiol: CH3OH + H2S → CH3SH + H2O Such reactions are conducted in the presence of acidic … See more There are several ways to name the alkylthiols: • The suffix -thiol is added to the name of the alkane. This method is nearly identical to naming an alcohol and is used by the IUPAC, e.g. CH3SH would be methanethiol. • The … See more Volatile thiols are easily and almost unerringly detected by their distinctive odor. Sulfur-specific analyzers for gas chromatographs are useful. Spectroscopic indicators are the D2O-exchangeable SH signal in the H NMR spectrum ( S is NMR-active but signals … See more Akin to the chemistry of alcohols, thiols form sulfides, thioacetals, and thioesters, which are analogous to ethers, acetals, and esters respectively. Thiols and alcohols are also very different in their reactivity, thiols being more easily oxidized than alcohols. Thiolates are more … See more
