Draw and name all constitutional isomers

  1. Jul 7, 2004 #1
    I am doing my Organic Chem homework and need help. It asks: Draw and name all constitutional isomers with formula C9H20 which have one quaternary carbon and one or more ethyl groups (there are three). What are they and how do I find them?

    Is C9H20 an alkane, alkene or alkyne ? Start with one ethyl group and figure out where you can stick this group on the main chain for it to still be called ethyl. Now fix the main chain by making sure it has a quaternary C.

    Start off and draw one isomer, and then you'll find it easier to get more.
