Dispersion Forces
weakest
Which type of force is hydrogen bonding?
Intermolecular force, Van der Waals force
Which type of force is a dipole-dipole interaction?
intermolecular, Van der Waals force
What are two other names for dispersion forces?
London dispersion forces
Induced dipole-dipole
Is hydrogen bonding stronger or weaker than dispersion forces?
stronger
Stronger dipoles result in ___ ___.
stronger interactions
Dispersion forces increase with ___ and ___.
Size and mass
Strong hydrogen bonding causes a high ___ ____.
surface tension
How can dipole-dipole interactions be predicted?
from electronegativity and molecular geometry
Are dispersion forces intramolecular forces or intermolecular forces?
Intermolecular forces
This is a Van der Waals force
Which bonds are hydrogen bonds commonly found in?
H-O, H-N, and H-F bonds
Dipole-dipole interactions result from what?
polar molecules
What happens to cause a dispersion force?
Electron fluctuations cause an instantaneous dipole in one molecule, which induces a dipole in a second molecule, leading to an attractive force.
Hydrogen bonding is the result of what?
A hydrogen atom bonded to a small electronegative atom. The hydrogen is exposed, resulting in a partial positive charge, which attracts electrons from other atoms.
