Coumpounds with a double and triple bond take the ending -enyne, and the double bond receives lowest-numbering priority. Can you figure it out now?

Second question: name the phenyl first.

I think the secind one is x-phenyl-octene.I'm noit sure about the first,though.My first guess would be 4,1-methynpentene,but i'm not sure...

I do not think you are correct about the first one...let's let the OP take a shot at it. Keep the ending I mentioned earlier in mind.

The second one is correct except no dash b/w the two terms; should be x-phenyloctene, AFAIK.
