Quizplus · Accepted Answer

In the IUPAC system of naming alkenes, the position of the double bond is always given the lowest possible number. This is regardless of the length of the carbon chain or the presence of substituents. The substituents are then named and listed in alphabetical order with their position number(s) indicating the position(s) on the carbon chain.
