Organic Sulfur Compounds: Definitions and Properties
Definitions
Organic Sulfur Compounds Organic sulfur compounds are a class of organosulfur compounds where sulfur is bonded to carbon. Key families are defined by their specific sulfur-containing functional groups.
Thiol (Mercaptan) An organosulfur compound containing a carbon-bonded sulfhydryl group (-SH), with the general formula R–SH (where R is an alkyl or other organic substituent).
- 1-Thiol: The -SH group is located at the terminal (end) carbon of the alkyl chain.
- 2-Thiol & 3-Thiol: The -SH group is located at the second or third carbon atom in the alkyl chain, respectively.
- Also known as mercaptan.
Sulfide (Thioether) An organic compound of the form R'–S–R'' (where R' and R'' represent alkyl or other organic substituents).
- Dialkyl Sulfide: A sulfide where R' and R'' are identical, linear alkyl groups.
- Methyl Alkyl Sulfide: A sulfide where R' is a methyl group (-CH₃) and R'' is any alkyl group.
- Ethyl Alkyl Sulfide: A sulfide where R' is an ethyl group (-C₂H₅) and R'' is any alkyl group.
- Isopropyl Alkyl Sulfide: A sulfide where R' is an isopropyl group (-CH(CH₃)₂) and R'' is any alkyl group.
- Diisoalkyl Sulfide: A sulfide where R' and R'' are identical isoalkyl groups.
Disulfide An organic compound of the form R'–S–S–R'' (where R' and R'' represent alkyl or other organic substituents). Features a sulfur-sulfur single bond.
Thiophene A heterocyclic compound with the molecular formula C₄H₄S. It consists of a stable, flat five-membered ring containing four carbon atoms and one sulfur atom.
Alkylthiophene A monosubstituted thiophene with one alkyl group attached to a carbon of the thiophene ring. Its general formula is CₙH₍₂ₙ₊₁₎C₄H₃S.
General Properties
The liquid density at 20°C of these organic sulfur compounds (e.g., thiols, sulfides, disulfides, thiophenes) can be compared to other organic classes like alkanes, alcohols, carboxylic acids, and amines. Density for these compounds is typically shown as a function of the total carbon number in the molecule.
