Intermolecular Forces

Front

What are intermolecular forces?

Back

Intermolecular forces are the forces of attraction or repulsion between neighboring particles (molecules, atoms, or ions). They play a crucial role in determining the physical properties of substances.

What are London Dispersion Forces?

Back

London Dispersion Forces are weak intermolecular forces that arise from temporary dipoles in molecules. They are present in all molecules, regardless of polarity.

Front

What is hydrogen bonding?

Back

Hydrogen bonding is a strong type of dipole-dipole interaction that occurs when hydrogen is bonded to highly electronegative atoms like nitrogen, oxygen, or fluorine.

Front

What are dipole-dipole interactions?

Back

Dipole-dipole interactions are attractive forces between the positive end of one polar molecule and the negative end of another polar molecule.

Front

Does CO2 exhibit hydrogen bonding?

Back

No, CO2 does not exhibit hydrogen bonding because it is a nonpolar molecule.

Front

Does CH4 exhibit hydrogen bonding?

Back

No, CH4 does not exhibit hydrogen bonding because it is a nonpolar molecule.

Front

Does HCl exhibit hydrogen bonding?

Back

No, HCl does not exhibit hydrogen bonding because it is a polar molecule but does not have hydrogen bonded to a highly electronegative atom.

Front

Does H2O exhibit hydrogen bonding?

Back

Yes, H2O exhibits hydrogen bonding due to the presence of hydrogen bonded to oxygen, a highly electronegative atom.

Front

What intermolecular forces are present in all polar molecules?

Back

Dipole-dipole interactions are present in all polar molecules.

Front

What is the strongest type of intermolecular force?

Back

Hydrogen bonding is generally considered the strongest type of intermolecular force.
