4.8 Intermolecular Forces Review

Front

What are intermolecular forces?

Back

Intermolecular forces are the forces that occur between molecules, influencing their physical properties such as boiling and melting points.

Front

What type of intermolecular force is present in H2S?

Back

Dipole-Dipole forces are present in H2S due to its polar nature.

Front

Which intermolecular force is the strongest in water (H2O)?

Back

Hydrogen bonding is the strongest intermolecular force in water.

Front

What type of intermolecular force is found in HCl?

Back

Dipole-Dipole forces are found in HCl due to its polar covalent bond.

Front

What are London dispersion forces?

Back

London dispersion forces are weak intermolecular forces that arise from temporary dipoles in molecules, present in all molecules but significant in nonpolar ones.

Front

What is the significance of molecular polarity in determining intermolecular forces?

Back

Molecular polarity determines the type and strength of intermolecular forces; polar molecules exhibit stronger forces like dipole-dipole and hydrogen bonding, while nonpolar molecules exhibit weaker London dispersion forces.

Front

What is the molecular formula of a compound with nonpolar molecules that is solid at room temperature?

Back

C30H62 is an example of a compound with nonpolar molecules that exists as a solid at room temperature.

Front

What is the primary factor responsible for the properties of nonpolar compounds?

Back

London dispersion forces are the primary factor responsible for the properties of nonpolar compounds.

Front

How do intermolecular forces affect boiling and melting points?

Back

Stronger intermolecular forces result in higher boiling and melting points, as more energy is required to overcome these forces.

Front

What is the difference between intramolecular and intermolecular forces?

Back

Intramolecular forces are the forces within a molecule (e.g., covalent bonds), while intermolecular forces are the forces between different molecules.
