Just by looking at its Lewis structure, how could you tell whether or not a molecule
could
have pi bonds?
Thanks in advance.

If the Lewis structure has multiple (i.e double or triple bonds) in it, than it has pi bonds. A double bond has one sigma and one pi bond and a triple bond has one sigma bond and two pi bonds.

Right. And from Lewis structure, multiple bonds mean multiple electron pair shared.
