Which of the Following is Not Considered a Van Der

Question

Which of the following is not considered a van der Waal's force?
A) dipole - dipole bond
B) dipole - induced dipole bond
C) induced dipole - induced dipole bond
D) ion - dipole bond

Accepted Answer

Ion-dipole bond is not considered a van der Waal's force because it involves an actual transfer of electrons between the ion and the polar molecule, while van der Waal's forces arise due to temporary fluctuations in the electron cloud of molecules.
