Intermediate IUPAC Nomenclature VI Alcohols and Ethers Alcohols: Alcohols have the general group R-OH. They are polar, moderately water soluble, and moderately acidic. They get higher priority than all hydrocarbons and haloalkanes IUPAC Nomenclature of alcohols follows these steps: 1) Find the longest chain of continuous carbons that includes the carbon attached to the alcohol . This is now the main chain. Name this chain as if it were a straight chain alkane. a. Drop the –ne ending and add –ol. This works for –enes and – ynes as well. 2) Count the carbons in the main chain left to right and right to left. The direction you first run into the carbon attached to the alcohol is the direction use to number the chain. Other substituents no longer matter only the alcohol determines direction. a. If the numbers are the same go to the next highest priority functional group or substituent and follow its priority rules. 3) Give each substituent a number according to which carbon it ʼ s attached to. Numbers for alkenes and alkynes correspond to the lower numbered of the two carbons in the bond. 4) List the substituents in alphabetical order in front of the main chain as you would in an alkane.
