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.

Front

Which type of intermolecular force is present in NH₃?

Back

NH₃ exhibits hydrogen bonding, a strong type of dipole-dipole interaction due to the presence of a highly electronegative nitrogen atom bonded to hydrogen.

Front

What is the boiling point of a substance influenced by?

Back

The boiling point of a substance is influenced by the strength of its intermolecular forces; stronger forces result in higher boiling points.

Front

Identify the type of intermolecular force in CO₂.

Back

CO₂ has London Dispersion Forces, which are weak forces arising from temporary dipoles in molecules.

Front

What type of intermolecular forces are present in noble gases?

Back

Noble gases primarily exhibit London Dispersion Forces due to their nonpolar nature.

Front

Explain ionic bonding.

Back

Ionic bonding involves the transfer of electrons from one atom to another, resulting in the formation of positively and negatively charged ions that attract each other.

Front

What type of intermolecular force is present in I₂, Br₂, and Cl₂?

Back

I₂, Br₂, and Cl₂ exhibit London Dispersion Forces due to their nonpolar diatomic nature.

Front

What is the significance of hydrogen bonding?

Back

Hydrogen bonding is significant because it greatly influences the properties of substances, such as the high boiling point of water compared to other similar-sized molecules.

Front

Define 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

What is the relationship between molecular size and London Dispersion Forces?

Back

As molecular size increases, London Dispersion Forces generally increase due to a larger electron cloud that can create temporary dipoles.
