Chemistry 118A Winter 2008 TA: Dani Solano How to name organic molecules 1) Determine the suffix 2) Determine the parent chain a. If two or more chains have identical length, the parent chain is the one with the greater number of substituents b. If two or more chains have identical length and equal numbers of substituents, the parent chain is the one that gives the simplest possible name (e.g. avoid parenthesis) 3) Determine the prefix 4) Combine prefix + suffix to give root name a. If no substituents Æ DONE 5) Name substituents a. If a substituent does not have a simple name, follow steps 1-5, then number starting at the point of attachment to the rest of the molecule, follow steps 7-9, and put the resulting name in parenthesis Æ continue to step 6 for the rest of the molecule 6) Number parent chain so that the first substituent has the lowest

Unformatted text preview: possible number a. If two substituents are in equivalent positions, use alphabetical order to determine lower number b. If two substituents are in equivalent positions and are the same, use the next substituent to determine numbering of the parent chain 7) Give each substituent a number in front of its name, separated by a hyphen a. If one substituent, add root name to the end Æ DONE b. If multiple identical substituents, combine numbers in order and separate each with a comma, then add the appropriate prefix to the substituent name (di, tri, tetra, etc.). c. If no other substituents, add root name to the end Æ DONE 8) Order substituents alphabetically (do not include prefixes such as di, tert, tetra, etc.) 9) Combine all substituents in order, then add root name to the end...
