Homework Help: Naming Organic Compounds

  1. Feb 7, 2013 #1
    1. The problem statement, all variables and given/known data

    Give an acceptable IUPAC name for these compounds.


    3. The attempt at a solution

    So the question is really on the 2nd problem in the picture but I need to reference the first one for my question.

    So my original guess on the 2nd problem was. Cis-3-secbutyl, 1-methylcyclopentane

    I looked up the answer and it was... Cis-1-methyl-3-(1-methyl)propylcyclopentane

    So I sort of understand how naming complex substituent groups work so I applied it to the first question and got... trans 1-(1-methyl)ethyl, 3-methylcyclohexane. The answer to that was trans-1-isopropyl-3-methylcyclohexane.

    So just to reiterate my question, is Cis-3-secbutyl,1-methylcyclopentane the same as Cis-1-methyl-3-(1-methyl)propylcyclopentane?

    If it's not I'd appreciate any help :D

    Yes. My gut says that "sec butyl" is more informative than 1-methylpropyl (since this is just a butyl chain), but IUPAC is wacky like that.
