Question
Rule 4: Write the name as a single word, using hyphens to separate separate numbers from numbers. numbers from letters and commas to a. If two or more different side chains are present, cite them in order followed by the parent name. ote: The non-hyphenated prefixes iso and neo are considered part of the alkyl-group name and are listed alphabetically under i and n, but the hyphenated prefixes sec- and tert- as in sec-butyl or tert- butyl are considered prefixes and are not used in alphabetizing so these would be listed alphabetically under b for butyl. b. If two or more identical side chains are present, use one of the prefixes di-, tri-, tetra-, and so forth. Don't alphabetize prefixes unless they are part of a complex substituent name. c. Precede the name of each substituent with its assigned number. d. Use hyphens to separate numbers from letters; use commas to separate numbers from each other e. The parent name follows the substituent list. Naming complex substituents: -complex substituent simple alkyl group parent chain simple simple-- alkyl grou alkyl group Any substituents that cannot be named as simple alkyl groups are considered to be complex substituents. There are two methods of naming complex substituents. i. The first method considers the complex branch to be numbered starting at its point of attachment to the parent chain. This results in the complex branch shown above being named as a substituted butyl group (4 carbons). specifically a (I-ethyl-2-methylbutyl) group to indicate the location of the branches on the butyl group.Explanation / Answer
You will have to cite them in ascending alphabetical order.
Butyl comes before Isopropyl.
At the same time, it does not matter if it is dimethyl.That time, too, ethyl comes before dimethyl.
Like, if a chain contains both methyl and butyl (eg, dimethylbutyl),that comes before ethyl.Because "d" comes before "E".
