IUPAC nomenclature for many multiple bonds

Message
[QUOTE="donaldparida, post: 5685198, member: 596616"] My previous Chemistry teacher while teaching IUPAC nomenclature said that the double bond is always given greater priority over the triple bond and the numbering of the carbon atom chain is done in such a way that the double bond gets the lowest possible number while my present Chemistry teacher says that the numbering of the carbon atoms is done in such a way that the multiple bond gets the lowest number whether it is the double bond or the triple bond (whichever multiple bond is nearest to the end when both the ends are considered, numbering is done from that end). On surfing through the various sites on the Internet, i came across the lowest sum of locants rule. I am confused and cannot understand how to number the carbon atoms for IUPAC nomenclature purposes when many multiple bonds are present in the molecule. What is the actual rule? [/QUOTE]
