Question

14 which intermolecular forces come from permanent bond dipoles? (select all that apply)
a london dispersion forces
b hydrogen bonding
c dipole interactions

Explanation:

• London Dispersion Forces: These are due to temporary electron - cloud distortions, not permanent bond dipoles.
• Hydrogen Bonding: It is a special case of dipole - dipole interactions. When a hydrogen atom is bonded to a highly electronegative atom (like N, O, F), a permanent dipole is created. The hydrogen bonding interaction is between these permanent dipoles.
• Dipole Interactions: Occur between molecules with permanent dipoles.

Answer:

B. Hydrogen Bonding, C. Dipole Interactions
