Question

Which statement best describes the intermolecular forces between H2

molecules and NH3 molecules in the liquid phase?
A. Dipole-dipole forces are the strongest force between H2
molecules, and Van der Waals forces are the strongest force
between NH3 molecules.
B. Van der Waals forces are the strongest force between H2
molecules, and hydrogen bonding is the strongest force between
the NH3 molecules.
C. Hydrogen bonding is the strongest force between H, molecules
and between NH3 molecules.
D. Van der Waals forces are the strongest force between H2
molecules and between NH3 molecules.

Answer 1

D. Van der Waals forces are the strongest force between H2

molecules and between NH3 molecules.

Step-by-step explanation:

Van der Waal’s forces are the forces which arises due to disturbance in the electron density of the molecule.

These are usually found in non polar molecules. Hence N2 is said to exhibit this force.

Out of these Van der Waals is the weakest force.
