Hydrogen bonding occurs when hydrogen is bonded to N, O, or F.  Which of the following has hydrogen bonding?

• CBr₄
• NO₂
• H₂S
• NH₃

Does H₂O have hydrogen bonding?

• yes
• no

• yes
• no

Does CH₄ have hydrogen bonding?

• yes
• no

Does NH₃ have hydrogen bonding?

• yes
• no

Which is the second strongest intermolecular force, after hydrogen bonding?

• dipole-dipole attraction

• LDF

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 LDF IMF's?

• I₂

• NH₃

• OCl₂

• SH₂
