Which of the following substances would have the greatest dispersion forces?

The dispersion forces are strongest for iodine molecules because they have the greatest number of electrons.

Does ethylene glycol have strong intermolecular forces?

The ethylene glycol can form hydrogen bonds on both ends of the molecule resulting in much stronger intermolecular forces and a higher boiling point.

Which intermolecular force is the strongest?

hydrogen bonding
The strongest intermolecular force is hydrogen bonding, which is a particular subset of dipole-dipole interactions that occur when a hydrogen is in close proximity (bound to) a highly electronegative element (namely oxygen, nitrogen, or fluorine).

Does ethylene glycol have London dispersion forces?

The answer is b. dispersion, and H-bonding. London Dispersion Force is available for ethylene glycol since the dispersion force is available to all…

How do you determine the strongest dispersion force?

Molecular Size

1. Larger and heavier atoms and molecules exhibit stronger dispersion forces than smaller and lighter ones.
2. In a larger atom or molecule, the valence electrons are, on average, farther from the nuclei than in a smaller atom or molecule.

What is the strongest intermolecular force found in carbon monoxide CO?

The dipole-dipole attractions between CO molecules are comparably stronger than the dispersion forces between nonpolar N2 molecules, so CO is expected to have the higher boiling point.

Is ethylene glycol intermolecular forces?

Ethylene glycol, HOH2C−CH2OH has two polar hydroxyl groups, and the dipoles line up from molecule to molecule. This constitutes a potent intermolecular force, which accounts for the high boiling point of ethylene glycol, 197.3 ∘C , and also its viscosity.

Which has stronger intermolecular forces water or ethylene glycol?

Since ethylene glycol has a stronger IMFA, its molecules in the liquid state will have difficulty escaping into the gas phase resulting in a lower vapor pressure than water. Moreover, the liquid molecules of ethylene glycol will be more attracted to each other making it more viscous than water.

What is the strongest intermolecular forces Why is it the strongest?

The strongest intermolecular forces are dipole-dipole interactions. A dipole-dipole force is when the positive side of a polar molecule attracts the negative side of another polar molecule. For this kind of bond to work, the molecules need to be very close to each other as they are in a liquid.

What is the strongest intermolecular force that occurs between molecules of CO2?

CO2 has polar bonds (O is much more electronegative than C) but the polar bonds ARE symmetrically opposite to one another so CO2 is not a polar molecule and does not have permanent dipole-dipole interactions. The strongest type of intermolecular forces are called hydrogen bonds.

What is the strongest IMF between two molecules of ethylene glycol?

Why do larger molecules have stronger dispersion forces?

Larger and heavier atoms and molecules exhibit stronger dispersion forces than smaller and lighter ones. In a larger atom or molecule, the valence electrons are, on average, farther from the nuclei than in a smaller atom or molecule. They are less tightly held and can more easily form temporary dipoles.

What type of intermolecular forces are present in F2 and HCl?

HCl is a polar molecule, F2 is not. The dipole present in HCl allows it to generate dipole-dipole interactions, while F2 is strictly nonpolar. The stronger intermolecular forces cause HCl to remain liquid until higher temperatures are reached. How do intermolecular forces compare with intramolecular forces in terms of strength?

How can I determine the strength of intermolecular forces?

When judging the strength of intermolecular forces in compounds that only exhibit weak van der Waals interactions, or London dispersion forces (LDF), you have to go by two things Molar mass – the size of the molecule in question – in your case, the longer the carbon chain and the bigger the molar mass, the stronger the LDFs will be;

How to measure the strength of the LDFs of a compound?

A measure of the strength of the LDFs will be the compounds’ boiling point. The stronger the dispersion forces, the higher the boling point will be. If you take into account the two rules I’ve mentioned, you’ll end up, in order of increasing boiling point, i.e increasing strength of LDFs, with

How do dipole dipoles affect intermolecular forces?

A stronger intermolecular force result when molecules have permanent dipoles. Polar molecules have a partially positive charge on one side and a partial negative charge on the other side–a separation of change called a dipole.
