Why does an ideal contact distance matter for van der Waals interactions?
Why does an ideal contact distance matter for van der Waals interactions?
- It allows for the stabilization of hydrogen bonds
- Too far a distance will result in no van der Waals interactions (correct)
- It enables the fleeting pull of opposite charges between molecules
- It prevents the formation of covalent bonds
