In the IUPAC system, alcohols are named by changing the ending of the parent alkane name to -ol. Learn Naming Thiols with free step-by-step video explanations and practice problems by experienced tutors. The systematic nomenclature of alcohols, ethers, and thiols is essential for accurately describing and communicating the structures of these important organic molecules in chemistry. You can replace the oxygen atom of an alcohol with a sulfur atom to make a thiol; similarly, you can replace the oxygen atom in an ether with S to make the corresponding alkyl sulfide. Practice Naming Thiols with a variety of questions, including MCQs, textbook, and open-ended questions. Thiols, also called mercaptans, are sulfur analogs of alcohols.

Alcohols are classified according to the number of carbon atoms attached to the carbon atom that is attached to the OH group. How to name thiols. ). Alcohols have higher boiling points than do ethers and alkanes of similar molar masses because the OH group allows alcohol molecules to engage in hydrogen bonding. The -SH group has priority over double bonds, nitro groups and halogens. Nomenclature of Thiols Thiols have long been commonly known as mercaptans. When naming a thiol, we give the carbon bonded to the SH group the lowest locant. Alcohols Thiols and sulfides are sulfur-containing organic compounds analogous to alcohols and ethers. As a net result, the R in the OR is regarded as the “substituent”, even though it is not. Logic. Like alcohols, thiols are weakly acidic; the p Ka of CH 3 SH, for instance, is 10.

The thiols are less soluble in water than are the alcohols and have lower boiling points than the corresponding alcohols. Thus many compounds have The IUPAC system chnames hydrocarbon in the as the parent, longest drops the ending -e and adds a new ending in nomenclature than alkenes, halogen and is given alkynes, a alkyl number lower than any of those groups. That name derives from the Latin term mercurium captans, or "seizing mercury," which refers to the ease with which thiols form mercury-based compounds.
