Which has higher priority in IUPAC naming: A double or a triple bond? given that both are located at the terminal/equivalent positions in the molecule.

My chemistry textbook says a double bond has a higher priority than a triple bond but I'm skeptical over it.

If someone can provide some more authentic source citing this rule, I'll be highly grateful.

EDIT: Drawing the hydrocarbon linear

Here is a wikipedia link https://en.wikipedia.org/wiki/IUPAC_nomenclature_of_organic_chemistry that refers to the IUPAC publication Nomenclature of Organic Chemistry (the Blue Book). – MaxW Oct 26 '17 at 18:24

Please, draw that alkyne linear. – orthocresol Oct 26 '17 at 18:28
@orthocresol Edit Made. Thanks for notifying! – Serotonin Oct 27 '17 at 01:41
@MaxW The priority table of functional grops given on wikpedia does not have alkene/alkyne in it. – Serotonin Oct 27 '17 at 01:44
@orthocresol I didn't knew this has been previously answered. Thanks! – Serotonin Oct 27 '17 at 01:57
@orthocresol is it always necessary to make alkynes linear? Are zig zag formulas not allowed for them? – Archer Oct 27 '17 at 15:48
@Abcd This should be a new question, really. See: https://doi.org/10.1351/pac200880020277 (p 345) – orthocresol Oct 27 '17 at 20:24
