HELLO THERE!
 
First, consider a fact:
When there are two functional groups present in a compound, like COOH (carboxylic acid group) and OH (alcohol group) are present at the same time, we name the compound checking the priority of the two. In the priority list, COOH comes before OH, so we use the prefix term (hydroxy) for OH, and suffix term (oic acid) for COOH while naming, and hence, the compound turns out to be an acid and not an alcohol!!
 
Thus, let’s come to your question. In the priority list, priority of Alkene > Alkyne > Alkane.
The prefix and suffix for singledouble and triple bonds are aneene, and yne.
If both double and triple bonds are present, then the compound will be called as an alkene (because priority of alkene is greater than that of alkyne).
 
Hope my answer is satisfactory.
Thanks!
