Question

Which intermolecular force would affect the boiling point the least

A. Hydrogen bonding
B. Van der Waals forces
C. lonic bonding
D. Dipole-dipole interactions

Answer 1

The intermolecular force that would affect the boiling point the least is London dispersion forces.

Step-by-step explanation:

The intermolecular force that would affect the boiling point the least is the London dispersion forces. London dispersion forces are the weakest intermolecular forces and are present between all particles, whether they are polar or nonpolar. They arise from the temporary shift in electron distribution that creates a temporary dipole in one molecule, inducing a dipole in the neighboring molecule. As a result, the strength of London dispersion forces increases with the size of the molecules involved and with the number of electrons present. These forces have the least impact on boiling point compared to other intermolecular forces like hydrogen bonding, dipole-dipole interactions, and ionic bonding.

Answer 2

The intermolecular force that least affects boiling point is van der Waals forces, more specifically, London dispersion forces, as these are the weakest and most temporary. So the correct option is B.

Step-by-step explanation:

The intermolecular force that would affect the boiling point the least is van der Waals forces, specifically London dispersion forces. These are the weakest form of intermolecular attraction and are less influential in determining a substance's boiling point compared to the stronger forces such as hydrogen bonding, dipole-dipole interactions, and ionic bonding. London dispersion forces are temporary, caused by fluctuations in electron distribution, and are more significant in larger atoms or molecules. Hence, among the options provided, the intermolecular force affecting the boiling point the least would be B. Van der Waals forces.
