Intermolecular Forces Vocab

Front

Hydrogen bonding is a special case of __________.

Back

dipole-dipole

Front

A molecule with two opposite charge regions.

Back

Dipole

Front

Intermolecular force between polar molecules.

Back

Dipole-dipole

Front

Intermolecular force when a polar molecule induces polarity in a nonpolar molecule.

Back

Dipole-induced dipole force

Front

Measure of atom's attraction for shared electrons, values 0.7-4.0, unitless.

Back

Electronegativity

Front

Force of attraction between molecules:

Back

Intermolecular Force

Front

Bond formed by attraction between oppositely charged ions; most polar type with complete transfer of valence electrons. Occurs if electronegativity difference ≥ 1.67.

Back

Ionic

Front

Intermolecular force of attraction from temporary dipoles inducing polarity in neighbors. Weakest type.

Back

London Dispersion Forces

Front

Stable particle of 2+ atoms.

Back

Molecule

Front

Bond with equal electron sharing; atoms have same electronegativity (≤ 0.4).

Back

Nonpolar Covalent
