IUPAC nomenclature assistance request

  1. Sep 15, 2007 #1
    The problem statement, all variables and given/known data
    My professor set us an online quiz in IUPAC nomenclature. I managed to get all of the problems correct, except for one. The graphic shows the molecule and my attempt at a solution.

    The attempt at a solution
    If you can't read what I typed in, it is:


    On my first attempt at this quiz, I tried using "s-butyl" instead of "sec-butyl" but I still missed it. My professor told us it wouldn't matter whether we used s-butyl or sec-butyl, but I decided to try both just to be sure. I have also double-checked my spelling and punctuation, but it all seems to be correct.

    I'm certain that the group on the left is s-butyl, there are two methyl groups so it is dimethyl, and there are 10 carbon atoms in the ring structure. Plus, I think I have the numbering correct (I did have some trouble with that initially). Any hints on what I'm doing wrong would be appreciated!

    I think the only thing I noticed first was that it's a cyclodecane... so maybe you can try 4-sec-butyl-1,1-dimethylcyclodecane.
