Intermolecular Forces IMF

Front

What are intermolecular forces?

Back

Intermolecular forces are attractions between neighboring molecules that influence physical properties such as boiling and melting points.

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 are the only forces in nonpolar molecules.

Front

What is a dipole-dipole interaction?

Back

Dipole-dipole interactions are attractions between polar molecules where the positive end of one molecule is attracted to the negative end of another.

Front

What is hydrogen bonding?

Back

Hydrogen bonding is a strong type of dipole-dipole interaction that occurs when hydrogen is bonded to highly electronegative atoms like nitrogen, oxygen, or fluorine.

Front

Which molecule has only London dispersion forces?

Back

I2 (Iodine) has only London dispersion forces.

Front

Which substance has the weakest intermolecular forces?

Back

CH4 (Methane) has the weakest intermolecular forces.

Front

What type of intermolecular forces are present in CO2?

Back

CO2 (Carbon Dioxide) exhibits London dispersion forces.

Front

What is the role of oxygen in hydrogen bonding?

Back

Oxygen can form hydrogen bonds due to its high electronegativity, attracting hydrogen atoms from other molecules.

Front

What are the main types of intermolecular forces?

Back

The main types of intermolecular forces are London dispersion forces, dipole-dipole interactions, and hydrogen bonds.

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.
