Which statement describes the strength of hydrogen bonding as an intermolecular force?

a. hydrogen bonding is the weakest intermolecular force.
b. hydrogen bonding is a medium-strength intermolecular force.
c. hydrogen bonding is the strongest intermolecular force.
d. hydrogen bonding is equal to the force between atoms within the molecule.

B.Hydrogen bonding is a medium-strength intermolecular force.

Explanation:

Hydrogen bonding forces are stronger than Van der waals forces hence they are more effective in binding molecules into larger units.

Ionic crystal lattice forces are strong electrostatic forces of attraction between oppositely charged ions arranged into a crystal lattice of ionic compounds. These forces are by far stronger than hydrogen bonding and Van der waals attraction.

The order of increasing strength of intermolecular forces is:

Van der Waals forces < Hydrogen bonding forces < Crystal Lattice forces.

Van der Waals forces are weak attractions joining non-polar and polar molecules together.

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
