Intermolecular forces

Front

What are intermolecular forces?

Back

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

Front

What is the strongest type of intermolecular force?

Back

Hydrogen bonding is the strongest type of intermolecular force, occurring between molecules that have hydrogen bonded to highly electronegative atoms like nitrogen, oxygen, or fluorine.

Front

What are London dispersion forces?

Back

London dispersion forces are weak intermolecular forces that arise from temporary dipoles in molecules, present in all substances regardless of polarity.

Front

What is the dominant intermolecular force in nonpolar molecules?

Back

London dispersion forces (LDF) are the dominant intermolecular force in nonpolar molecules.

Front

What type of intermolecular force is present in polar molecules?

Back

Polar molecules primarily experience dipole-dipole forces and may also exhibit hydrogen bonding if applicable.

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.

Front

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

Back

Larger molecules have stronger London dispersion forces due to increased polarizability, leading to higher boiling points.

Front

What is a dipole-dipole force?

Back

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

Front

What is hydrogen bonding?

Back

Hydrogen bonding is a specific type of dipole-dipole interaction that occurs when hydrogen is bonded to highly electronegative atoms like N, O, or F.

Front

Which type of intermolecular force is responsible for the high boiling point of water?

Back

Hydrogen bonding is responsible for the high boiling point of water.
