This organic chemistry video tutorial provides a basic introduction into naming alcohols using IUPAC Nomenclature. Other examples of IUPAC nomenclature are shown below, together with the common names often used for some of the simpler compounds. Alcohols are molecules that contain a hydroxyl […] 2. 1. Because OH is the functional group of all alcohols, we often represent alcohols by the general formula ROH, where R is an alkyl group. 1) The longest continuous chain, containing the -OH group will be the parent chain. 2) Number the parent chain, such that the carbon bearing the -OH group has the lowest number.. 3) Change the -e of the alkane to -ol.. is an organic compound with a hydroxyl (OH) functional group on an aliphatic carbon atom. Ethers Naming Ethers. We get the name of any alcohol by replacing the last ‘e’ from the name of the corresponding alkane by the suffix ‘–ol’. As noted in Chapter 4 "Covalent Bonding and Simple Molecular Compounds", an alcohol An organic compound with an OH functional group on an aliphatic carbon atom. The common name of an alcohol combines the name of the alkyl group with the word alcohol. Naming Alcohols - This video tutorial takes you step by step through the naming of an organic compound containing a hydroxyl or 'OH' functional group. When naming alcohols, we follow the rules for naming alkanes, except:. Naming an alcohol does require a few steps, but if you know how to name alkanes, then you’ll have no problems. https://www.onlinemathlearning.com/naming-alkenes-alcohol.html Naming Alcohols STEP 1: Name the parent compound. Classifying and naming alcohols is fairly straightforward. Thiols. Alcohols. For the mono-functional alcohols, this common system consists of naming the alkyl group followed by the word alcohol. Part of a nomenclature Video Series! 3. Common names often incorporate obsolete terms in the naming of the alkyl group; for example, amyl is frequently used instead of pentyl for a five-carbon chain. Example: CH 3-CH 2-OH is methylcarbinol and CH 3-CH 2-CH 2-OH is Ethylcarbinol. For example, to classify an alcohol, you just need to know where the hydroxyl group is in the alcohol molecule. STEP 2: Number the carbon atoms in the main chain. The parent chain is now the longest chain that has the hydroxyl group, even if there are longer carbon chains available. Basic IUPAC nomenclature-Alcohols (See the home page for parent root names, prefixes & suffixes.). Find the longest chain that has the hydroxyl substituent attached (replace the -e ending with –ol). Number the carbon chain in the direction that gives the smallest number to the carbon bonded to the hydroxyl group. An alcohol is an organic compound that contains the hydroxyl group ( – OH). IUPAC System: In IUPAC nomenclature, we term the alcohols as Alkanols. Alcohols Naming and Drawing Alcohols Properties of Alcohols Reactions Involving Alcohols 2. Chapter 3 Alcohols, Phenols, and Ethers 6 11 Examples: Naming Alcohols and Phenols • Draw and name all of the possible isomers of butanol (C4H10O) 12 Nomenclature of Alcohols and Phenols • If there is more than one OH group, a counting prefix (di-, tri-, tetra-, etc.) Examples include simple and substituted alcohols, saturated and cyclic alcohols. If the alkyl group is complex, the common name becomes awkward and the IUPAC name should be used. For example: (CH 3) 2 C=CHCH(OH)CH 3 is 4-methyl-3-penten-2-ol.
