U1 - Intermolecular Forces of Attraction

Question 1

•Ion-Ion

Answer 1

• Attraction between two ions
• (+) to (-)
• Strongest (1/7)

Question 2

•Ion-Dipole

Answer 2

• Attraction between a dipole and ion
• d+/- and (-)/(+)
• Will re-orient itself to attract
• Strong (2/7)

Question 3

•Dipole-Dipole

Answer 3

• Attraction between two polar compounds
• d+/- and d-/+
• Medium Stength (4/7)

Question 4

•Hydrogen Bonding

Answer 4

•Type of dipole-dipole attraction
•Between a hydrogen (attached to O, N, or F) and another O, N, or F
•Medium Strength (3/7)
–stronger than dipole-dipole, weaker than ion-dipole

Question 5

•Ion-Induced/Dipole Induced Attraction

Answer 5

• Attraction of a non-polar compound to an ion (or polar compound) caused by e- movement
• Weak (5/7; 6/7)

Question 6

•London-dispersion

Answer 6

• Momentary attraction between two non-polar compounds as e- move into perfect orientation
• Weakest (7/7)

Question 7

•Intermolecular Forces of Attraction

Answer 7

•Attractive forces between compounds and other compounds
