Answer 2

Answer:

Should it be named pent-1-en-4-yne or pent-1-yn-4-ene?However, according to the italicised portion of the quoted text, the double bond is considered to have the higher priority, and the name would correctly be pent-1-en-4-yne.

Note that the final "-e" from "-ene" is dropped if the following suffix begins with a vowel or "y," and is retained if the suffix begins with a consonant.
