IUPAC Nomenclature Find the longest carbon chain containing the carbon with the -oh group Drop the -e from the alkane name, add o Number the chain, starting from the end closest to the-Oh group Number and name all substituents, = Chapter 10
Chapter 10 5 IUPAC Nomenclature • Find the longest carbon chain containing the carbon with the -OH group. • Drop the -e from the alkane name, add - ol. • Number the chain, starting from the end closest to the -OH group. • Number and name all substituents. =>
