Hydroxyl Group Substitution - Chemistry LibreTexts

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 or a sulfhydryl group, or a sulfanyl group. Thiols are the sulfur analogue of alcohols (that is, … 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 … See more There are several ways to name the alkylthiols: • The suffix -thiol is added to the name of the alkane. This … 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 Odor Many thiols have strong odors resembling that of garlic. The odors of thiols, particularly those of low molecular weight, are often strong and repulsive.

WebJul 1, 2024 · In the alcohol functional group, a carbon is single-bonded to an OH group (the OH group, by itself, is referred to as a hydroxyl). Except for methanol, all alcohols can be … The prefix thio-, when applied to a chemical, such as an ion, means that an oxygen atom in the compound has been replaced by a sulfur atom. This term is often used in organic chemistry. For example, from the word ether, referring to an oxygen-containing compound having the general chemical structure R−O−R′, where R and R′ are organic functional groups and O is an oxygen atom, comes the word thioether, which refers to an analogous compound with the general structure R−…

WebThe redox reaction of thiol is mentioned below. 2 R–SH + Br 2 → R–S–S–R + 2 HBr. Reagents such as hydrogen peroxide or sodium hypochlorite can also produce sulfonic acids. R–SH + 3 H 2 O 2 → RSO 3 H + 3 H 2 O. In the presence of a catalyst, oxidation can be affected by oxygen. 2 R–SH + 1 ⁄ 2 O 2 → RS–SR + H 2 O. WebThe prefix mercapto-is placed before the name of a compound if the ―SH group is to be named as a substituent, as in mercaptoacetic acid, HSCH 2 COOH.
