The acetylene one is now ok, you get

and ethane.

Now do the same for the alcohol, replace the O-H by O^-Na⁺ and the NH₂^- by NH₃.

So just this? Why doesn't this other example do that? Should I have put the Na on the C^-?

PS - thank you so much, btw @_@ hah

Yes, associate the Na⁺ with the acetylene.
It's as simple as that!
