IUPAC naming for a sidechain with double bond?

  1. Jul 18, 2012 #1
    As shown in this picture.

    How would you do the naming for a sidechain that has double bonds?

    Or does the double bond take priority over the length of the chain?

    Indeed, DrDu. Chemdraw confirms that it's 3,3-dimethyl-5-methyleneheptane.
