Alcohols, nomenclature tertiary

In the IUPAC system of nomenclature, the suffix for alcohols is -ol. Alcohols are classified as primary, secondary, or tertiary depending on whether one, two, or three organic groups are attached to the hydroxyl-bearing carbon. The nomenclature of alcohols and phenols is summarized in Secs. 7.1-7.3. 

The primary (1), secondary (2 ), tertiary (3) and quaternary (4) nomenclature is used in a number of situations to define a carbon centre, or to define functional groups like alcohols, halides, amines and amides. Identifying functional groups in this way can be important because the properties and reactivities of these groups vary depending on whether they are primary, secondary, tertiary or quaternary. 

Name the following alcohols according to the lUPAC nomenclature system. Indicate stereochemistry (if any) and label the hydroxy groups as primary, secondary, or tertiary. 

The nomenclature of amines differs from that of the alcohols. The des nations primary, secondary, and tertiary refer to the number of substituents on the ammonia nitrogen ... 

An example using prostaglandin nomenclature is Misoprostol, (RS)-16-hydroxy-16-methylPGEi methyl ester, shown in Figure 6.63. PGEj is drawn as described above but with two substituents at the 16-position. The stereochemical designator (RS) preceding the name refers to the new chiral center formed by the tertiary alcohol and indicates that the compound is a mixture of both stereoisomers at that site (a mixture of diastereomers). Finally, the carboxylic acid is derivatized as a methyl ester to complete the structure of Misoprostol.
