Tables and figures showing the liquid density at 20°C for different groups of organic sulfur compounds including thiols, dialkyl sulfides, methylalkyl sulfides, ethyl alkyl sulfides, isopropyl alkyl sulfides, diisoalkyl sulfides, dialkyl disulfides, and alkylthiophenes, compared to alkanes, alcohols, acids and amines as function of carbon number.

Compound TypeMolecular Formula PatternDescription
ThiolR-SHOrganosulfur compound with carbon-bonded sulfhydryl group. R represents alkyl group. 1-thiol has -SH at end of chain, 2-thiol at second carbon, 3-thiol at third carbon.
Dialkyl SulfideR'-S-R''Sulfide where R' and R'' are linear alkyl groups of the same length.
Methyl Alkyl SulfideCH3-S-R''Sulfide where R' is methyl and R'' is any alkyl group.
Ethyl Alkyl SulfideC2H5-S-R''Sulfide where R' is ethyl and R'' is any alkyl group.
Isopropyl Alkyl Sulfidei-C3H7-S-R''Sulfide where R' is isopropyl and R'' is any alkyl group.
Diisoalkyl Sulfidei-R'-S-i-R''Sulfide where R' and R'' are isoalkyl groups of the same length.
Dialkyl DisulfideR'-S-S-R''Organic compound with disulfide linkage where R' and R'' are alkyl groups.
ThiopheneC4H4SHeterocyclic compound with stable flat five-membered ring.
AlkylthiopheneCnH(2n+1)C4H3SMonosubstituted thiophene with one alkyl group attached to the ring.
AlkaneCnH2n+2Acyclic saturated hydrocarbon. Also called paraffin.
AlcoholR-OHOrganic compound with hydroxyl functional group bound to saturated carbon.
Carboxylic AcidR-COOHOrganic compound containing carboxyl group.
AmineR-NH2, R',R''-NH, or R',R'',R'''-NCompound with basic nitrogen atom. Primary (1-amine), secondary, or tertiary forms.
