3.1

Question 1

Cohesive Force

Answer 1

Force of attraction between identical molecules

Question 2

Dipole-Dipole Attraction

Answer 2

Intermolecular attraction between two permanent dipoles

Question 3

Dispersion Force

Answer 3

Attraction between two rapidly fluctuating, temporary dipoles; significant only when particles are very close together

Question 4

Induced Dipole

Answer 4

Temporary dipole formed when the electrons of an atom or molecule are distorted by the instantaneous dipole of a neighboring atom or molecule

Question 5

Instantaneous Dipole

Answer 5

Temporary Dipole that occurs for a brief moment in the time when the electrons of an atom or molecule are distributed assymetrically

Question 6

Intermolecular Force

Answer 6

Non covalent attraction force between atoms, and/or ions

Question 7

Molecular Solid

Answer 7

Solid composed of neutral molecules held together by intermolecular forces of attraction

Question 8

Polarizability

Answer 8

Measure of the ability of a charge to distort a molecule’s charge distribution

Question 9

Van der Waals Force

Answer 9

Attractive or repulsive force between molecules, including dipole-dipole, dipole-induced dipole, and London dispersion forces; does not include forces due to covalent or ionic bonding, or the attraction between ions and molecules
