Which is expected to have the largest dispersion forces
What is expected to have the largest 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.

Which is expected to have the largest London dispersion forces?
So if we take a look, C 12 h six has a lot more elements than everyone else. When you add them all up that way, it would be greater than all the other compounds. Therefore, this has the highest mass, therefore have the strongest London dispersion forces, so option B would be the correct choice.
Which molecule would have the largest dispersion forces between its molecules?
molecules? We know that while London Dispersion forces are weak, they can increase in strength. I2 has the greatest forces because its large atomic radius allows it to be the most polarizable.
Does HBr exhibit dispersion forces?
HBr is a polar molecule: dipole-dipole forces. There are also dispersion forces between HBr molecules.
Which molecule would have the largest dipole?
The larger the difference in electronegativities of bonded atoms, the larger the dipole moment. For example, NaCl has the highest dipole moment because it has an ionic bond (i.e. highest charge separation).

Which molecule has the largest net dipole moment?
The molecule with the largest dipole moment is HF.
Which has a large London dispersion forces co2 or CO?
CO has two C-O bonds. The dipoles point in opposite directions, so they cancel each other out. Thus, although CO₂ has polar bonds, it is a nonpolar molecule. Therefore, the only intermolecular forces are London dispersion forces.
