IMF and Naming/Formulas Review

Does HCl have hydrogen bonding?

• yes
• no

Does CH₄ have hydrogen bonding?

• yes
• no

All molecules have London forces between them, but dipole-dipole and hydrogen bonding are so much stronger that when they are present we can ignore London forces.  Which of these has ONLY London forces?

• I₂
• NH₃
• OCl₂
• SH₂

Which substance would have the weakest intermolecular forces of attraction?

• CH₄

• NaCl

• H₂O

• MgF₂

Intermolecular forces for: NH₃

• Dispersion Force

• Dipole dipole

• Hydrogen bonding

Which substance has the weakest intermolecular forces?

• Substance A, boiling point of 75 °C

• Substance B, boiling point of 105 °C

• Substance C, boiling point of 25 °C

• Substance d, boiling point of 45 °C

Intermolecular forces for: CO₂

• Dispersion Force

• Dipole dipole

• Hydrogen bonding

Rank these in order of strength:

What information do we look for on the periodic table if we  want to examine intermolecular forces?

• atomic mass
• atomic number
• electronegativity
• ionization 

Intermolecular forces are the forces

• within molecules
• between molecules
