Intermolecular forces review

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 type of intermolecular force is present in ammonia (NH3)?

Back

Hydrogen bonding is the predominant intermolecular force in ammonia (NH3).

Front

Which substance has the lowest boiling point: CaCl2, PH3, Cl2, or N2?

Back

N2 has the lowest boiling point among the given substances.

Front

Which substance has the weakest intermolecular forces of attraction: CH4, NaCl, H2O, or MgF2?

Back

CH4 has the weakest intermolecular forces of attraction.

Front

What type of intermolecular force is present in hydrogen fluoride (HF)?

Back

Hydrogen bonding (H-bond) is the primary intermolecular force in hydrogen fluoride (HF).

Front

Does methane (CH4) exhibit hydrogen bonding?

Back

No, methane (CH4) does not exhibit hydrogen bonding.

Front

What are London dispersion forces?

Back

London dispersion forces are weak intermolecular forces that arise from temporary dipoles in molecules due to the movement of electrons.

Front

What is dipole-dipole interaction?

Back

Dipole-dipole interaction is an intermolecular force that occurs between polar molecules, where the positive end of one molecule is attracted to the negative end of another.

Front

What is the significance of hydrogen bonding in water (H2O)?

Back

Hydrogen bonding in water is responsible for its high boiling point, surface tension, and unique properties that support life.

Front

How do intermolecular forces affect boiling points?

Back

Stronger intermolecular forces result in higher boiling points, as more energy is required to separate the molecules.
