Which of the following best describes very weak, brief attractions between neutral atoms?
A
Dipole-dipole interactions
B
Hydrogen bonding
C
London dispersion forces
D
Ionic bonds
Verified step by step guidance1
Understand that the question is asking about the type of intermolecular force characterized by very weak and brief attractions between neutral atoms.
Recall that dipole-dipole interactions occur between molecules that have permanent dipoles (polar molecules), so they are not the weakest or briefest forces.
Recognize that hydrogen bonding is a special, relatively strong type of dipole-dipole interaction involving hydrogen bonded to highly electronegative atoms like N, O, or F, so it is stronger and more specific than the forces described.
Identify that ionic bonds are strong electrostatic attractions between ions, not neutral atoms, so they do not fit the description of weak, brief attractions between neutral atoms.
Conclude that London dispersion forces (also called induced dipole-induced dipole interactions) are the very weak, temporary attractions that arise due to momentary fluctuations in electron distribution in neutral atoms or nonpolar molecules, matching the description given.
