Quick question: Hydrocarbon nomenclature

  1. Jul 2, 2009 #1
    I just have a quick question about hydrocarbon nomenclature:

    When picking the "parent chain", I know that you're supposed to pick the one with the longest carbon chain... does the parent chain always have to have the double/triple bonds? Or can the double/triple bonds be located in a sidechain?

    Also, when prioritizing alkyl groups, what has a higher priority - methyl, ethyl, propyl, etc. Or do you just prioritize these straight chain alkyl side groups by alphabetical order?

    From what I remember of organic nomenclature the parent must always contain the double or triple. You cannot put as a side-chain. As for alkyl groups you just list them alphabetically.
