Hi.
When comparing the relative bond strengths, I'm aware that Covalent Bonds > Polar Interactions > Van-der Waals in terms of strongest to weakest. However, I'm not sure where pi-pi interactions fits in this. Is it the strongest bond strength amongst these 4 types of bonds? Any help would be appreciated. Thanks!

Assuming you mean intermolecular interactions between molecules that have pi bonds, yes?

From the start you should be able to specify where they are relative to covalent bonds, at the least.
