How does alkane nomenclature work?

I know the prefixes and suffixes, but if something is called propene for example, would it have only ONE double bond?

And if it’s called propYNE, would it only have one triple bond? And propane would have any number of single bonds?

    An alkane with two double bonds is called a diene. The simplest is propadiene.

    For three double bonds it's a triene, and so on.

    Propene means three carbon atoms and one double bond.

    Likewise for triple bonds:

    Two triple bonds make a diyne. Three triple bonds make a triyne.

    Propyne has one triple bond.
