  • What is the first step in naming an alkane compound?
    Find the longest continuous carbon chain and assign a root name based on its length.
  • How do you choose the root name for an alkane with 6 carbons?
    The root name is hexane for a 6-carbon chain.
  • If two chains of equal length are present, which chain should you choose as the parent chain?
    Choose the chain that gives the most substituents.
  • From which end should you number the carbon chain when naming alkanes?
    Number the chain from the end closest to a substituent.
  • How are substituents listed in the name of an alkane?
    Substituents are listed alphabetically, each with a number indicating their position.
  • What prefix is used if two methyl groups are attached to the parent chain?
    The prefix 'dimethyl' is used for two methyl groups.
  • What is the correct way to write the name for an alkane with two methyl groups on carbons 2 and 4?
    Write it as 2,4-dimethyl followed by the root name of the parent chain.
  • How do you indicate the number of identical substituents in an alkane name?
    Use numerical prefixes like di-, tri-, tetra-, etc., before the substituent name.
  • What is the root name for an alkane with 10 carbons?
    The root name is decane.
  • If a substituent has two carbons, what is its name?
    A two-carbon substituent is called ethyl.
  • How do you decide the correct numbering when two possible numberings give the same chain length?
    Choose the numbering that gives the lowest numbers to the substituents.
  • What is a substituent in the context of alkane nomenclature?
    A substituent is a group attached to the parent chain that is not part of the longest chain.
  • How should the final name of an alkane be written regarding spaces?
    The name should be written as one word, with no spaces between prefixes and the root name.
  • If you have a butyl group on carbon 5, how should it be written in the name?
    It should be written as 5-butyl.
  • Why is it important to number the chain from the end closest to a substituent?
    This ensures that the substituents receive the lowest possible numbers in the name.
