How strong is an alkene as a nucleophile?

Hii...


When I do reactions, I'm often thinking about the pka but as a base, how strong is an alkaline? I found myself having a slight crisis. I can look up the pka of the hydrogen of an alkaline but what if the carbons are all bonded? The pi electrons can still attack right? How strong/weak is that?

Thanks..!
