N₂.

Front

The weaker the intermolecular forces of a substance, the _____________ the boiling point.

Back

lower.

Front

Type of intermolecular force present in I₂, Br₂, and Cl₂.

Back

London Dispersion Forces.

Front

Define intermolecular forces.

Back

Forces that occur between molecules, affecting their physical properties.

Front

What are hydrogen bonds?

Back

Strong dipole-dipole attractions between molecules that contain hydrogen bonded to highly electronegative atoms like N, O, or F.

Front

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

Back

Larger molecules have stronger London dispersion forces due to increased polarizability.

Front

What is a dipole-dipole interaction?

Back

Attraction between the positive end of one polar molecule and the negative end of another polar molecule.

Front

How do intermolecular forces affect boiling points?

Back

Stronger intermolecular forces result in higher boiling points.
