Intermolecular Forces

Question 1

Dipole-Dipole Forces

Answer 1

Only in polar molecules, permanent dipoles

Question 2

Hydrogen Bonding

Answer 2

Occurs in polar molecules containing hydrogen atoms bonded to (N, O, or F)

Question 3

Ion-Dipole Forces

Answer 3

Present in a mixture of an ionic compound and polar compound

Question 4

Ion-Ion Forces

Answer 4

Present in ionic compounds, related to lattice energy in a compound

Question 5

Trends in lattice energy

Answer 5

Lattice energy is higher for higher charges and larger for smaller ions

Question 6

Physical Properties

Answer 6

All related to lattice energy except solubility and vapor pressure

Ionic solids generally have higher melting points than molecular solids

Question 7

Dispersion Forces

Answer 7

Attraction between the temporary dipoles
