Multiple Choice
Which of the following is the strongest type of intermolecular force?
A
Hydrogen bonding
B
London dispersion forces
C
Ion-dipole interactions
D
Dipole-dipole interactions
Verified step by step guidance
1
Identify the types of intermolecular forces listed: London dispersion forces, ion-dipole interactions, dipole-dipole interactions, and hydrogen bonding.
Recall that London dispersion forces are the weakest and arise from temporary fluctuations in electron distribution in molecules.
Understand that dipole-dipole interactions occur between polar molecules due to permanent dipoles, which are stronger than London dispersion forces.
Recognize that ion-dipole interactions occur between ions and polar molecules and are generally stronger than dipole-dipole interactions.
Know that hydrogen bonding is a special, particularly strong type of dipole-dipole interaction that occurs when hydrogen is bonded to highly electronegative atoms like nitrogen, oxygen, or fluorine, making it the strongest intermolecular force among the options given.
