Which liquid has the highest intermolecular forces?

Besides mercury, water has the highest surface tension for all liquids. Water’s high surface tension is due to the hydrogen bonding in water molecules. Water also has an exceptionally high heat of vaporization.

Which liquid has the strongest intermolecular forces?

Water has the strongest intermolecular forces (hydrogen bonds) of all the substances used.

What is the highest intermolecular force?

Dipole-dipole interactions are the strongest intermolecular force of attraction.

Which of these substances has the strongest intermolecular forces?

H2O is the substance that has the strongest intermolecular forces.

Which has stronger intermolecular forces liquid water or water vapor?

Liquid water because it needs higher temperature to break the intermolecular forces between its molecules while the water vapor has lower intermolecular forces due to its gas nature wherein its molecules are fast and free-moving.

What are the 3 intermolecular forces from weakest to strongest?

There are three different types of intermolecular forces in terms of strength. They are (strongest to weakest) hydrogen bonding, dipole-dipole and Van der Waals’ forces.

Which liquid has the weakest intermolecular forces?

  • Oil- Only London Dispersion Forces (the weakest intermolecular force)
  • Water- London Dispersion, Dipole-Dipole, and Hydrogen Bonding.

What is the weakest to strongest intermolecular force?

In order from strongest to weakest, the intermolecular forces given in the answer choices are: ion-dipole, hydrogen bonding, dipole-dipole, and Van der Waals forces.

Which attractive force is the weakest?

Dispersion forces are the weakest intermolecular force (one hundredth-one thousandth the strength of a covalent bond), hydrogen bonds are the strongest intermolecular force (about one-tenth the strength of a covalent bond).

What is the strongest intermolecular force in CH4?

Therefore the strongest intermolecular forces between CH4 molecules are Van der Waals forces. Hydrogen bond are stronger than Van der Waals forces therefore both NH3 and H2O will have higher boiling points than CH4.

Which hydrogen bonding is the strongest?

The strength of hydrogen bond depends upon the coulumbic interaction between the electronegativity of the attached atom and hydrogen. Fluorine is the most electronegative element. F−H−−−F bond will be strongest H bond.

What are the 4 types of intermolecular forces?

There are four major classes of interactions between molecules and they are all different manifestations of “opposite charges attract”. The four key intermolecular forces are as follows: Ionic bonds > Hydrogen bonding > Van der Waals dipole-dipole interactions > Van der Waals dispersion forces.

Why hydrogen bonding is the strongest intermolecular force?

Hydrogen bonds are strong intermolecular forces created when a hydrogen atom bonded to an electronegative atom approaches a nearby electronegative atom. Greater electronegativity of the hydrogen bond acceptor will lead to an increase in hydrogen-bond strength.

Why does water have the strongest intermolecular force?

Hydrogen Bonding. A property of water is that it has strong intermolecular forces as a result of hydrogen bonding and the dipole moments created by the strong electronegative oxygen and the hydrogen. … The energy required to break these bonds accounts for the relatively high melting point of water.

What type of intermolecular forces are active in the liquid state of hi?

c) In HI, there is dipole-dipole interaction but is less than London Dispersion (non-polar molecules).

What happens when you increase the intermolecular forces of a liquid?

As the intermolecular attraction increases, • The vapor pressure ( the pressure of the vapor that is in equilibrium with its liquid) decreases • The boiling point ( the temperature at which the vapor pressure becomes equal to the pressure exerted on the surface of the liquid) increases • Surface tension ( the …
