Here we look at alkanes with halogen and hydroxyl substituents. Substituents are named and numbered as in alkanes. Names of Alcohols. The number that indicates the position of the OH group is prefixed to the name of the parent hydrocarbon, and the -e ending of the parent alkane is replaced by the suffix -ol. ... Find and name the substituents. IUPAC: in IUPAC replace -e of Alkane with -ol Common names: put alkyl group then alcohol. 8 Examples: Naming Alcohols and Phenols • Provide acceptable IUPAC names for the following compounds: CH3 OH CH3 CH2 OH CH3 CH2 CH2 OH CH3 CH CH3 OH CH3 CH CH2 OH CH3 Now, let's look at how to name alcohols with additional substituents. Combine the name and location for other groups, the hydroxyl group location, and the longest chain into the final name. Other substituents are not included in naming alcohols in IUPAC nomenclature. Step 4. Step 3. • Step 5. Identify the substituents. This is the brief summary of the steps: Step 1. Step 2. Identify the parent chain. The molecule shown in the next figure has two methyl group substituents — one at the number-three carbon and one at the number-five carbon. You can use the alkane name and simply add the word 'alcohol' after it. Number the parent chain. Step 1 Name longest chain with -OH group Step 2 Number longest chain closer to -OH group Step 3 Name substituents from -OH Step 4 Name a cyclic alcohol as cyclo. The presence of other substituents in alcohol is indicated by their names and numerical positions, always keeping the lowest possible number for the hydroxyl group. The generic IUPAC name for alcohol is alkanols, and they are represented in reactions by the general formula R-H. You must then locate and identify all the substituents that stick off of the parent chain, including multiple and complex branches. Disubstituted benzene rings can be named based on the relative positions of the substituents: the prefix ortho– is used if the substituents occupy adjacent positions on the ring (1,2), meta– is used if the substituents are separated by one ring position (1,3), and para– if they are found on opposite sides of … Put everything together having the substituents in alphabetical order. Naming alkenes follows the same rules we discussed earlier for the IUPAC nomenclature rules for alkanes. 3) the ending which specifies what functional group is present in the structure being named. Locate and name any other substituents. Guide to Naming Alcohols. For example, to classify an alcohol, you just need to know where the hydroxyl group is in the alcohol molecule. Classifying and naming alcohols is fairly straightforward. When naming a branched alkane, you first need to locate and number the parent (longest) chain. IUPAC Nomenclature for Alcohols More IUPAC nomenclature! (In cyclic alcohols, the carbon atom bearing the OH group is designated C1, but the 1 is not used in the name.) An alcohol with additional substituents Start by finding the longest carbon chain that includes the alcohol group. The systematic methods of naming alcohols follow a similar procedure and the names have three main parts: 1) specifying the information about the substituents, 2) specifying the information about the parent chain, and.
