Which has higher boiling point?

A. Alkenes
B. Alkadienes
I think my answer would be A because it contains 1 double bond (1 pi bond)

I would agree with you but I would say it contains ONLY 1 double bond.
Yes.. So alkadiene is much more volatile than alkene?
I don't know that I would say MUCH more volatile. That depends upon what two or three alkenes/alkadienes you are comparing. Also it may depend more upon the intermolecular forces than on the number of pi bonds.
