Back

Ionic forces.

Front

What intermolecular forces are present in ammonia (NH3)?

Back

Hydrogen bonding.

Front

What does ionic bonding involve?

Back

The transfer of electrons.

Front

What type of intermolecular force is present in silicon dioxide (SiO2)?

Back

Covalent network.

Front

Define hydrogen bonding.

Back

A strong type of dipole-dipole attraction between molecules that have a hydrogen atom bonded to a highly electronegative atom (like N, O, or F).

Front

What are dipole-dipole forces?

Back

Attractive forces between the positive end of one polar molecule and the negative end of another polar molecule.

Front

What is the significance of London dispersion forces?

Back

They are weak intermolecular forces that arise from temporary dipoles in molecules, significant in nonpolar substances.

Front

How do intermolecular forces affect boiling points?

Back

Stronger intermolecular forces result in higher boiling points.

Front

What is the relationship between molecular size and London dispersion forces?

Back

Larger molecules have stronger London dispersion forces due to increased polarizability.
