Why F2 has a lower boiling point than Br2?

From the order of boiling points, we can determine that the VdW forces in Br2 must be stronger than the VdW forces in F2 – this is because Br2 has more electrons which can create temporary dipoles.

Why does I2 have such a high boiling point?

Iodine is the biggest atom with the most electrons and hence its electron cloud is the most polarisable. I2 therefore has the strongest dispersion forces and the highest boiling point.

Is F2 stronger than I2?

and F2 will have the weakest. Correspondingly, I2 will have the highest boiling point and F2 will have the lowest boiling point.

Why does LiF have a higher boiling point than F2?

Finally, LiF is ionic and held together by ionic interactions, the strongest IMFs of all. The stronger the IMFs holding molecules together, the more energy is required to separate the molecules and, thus, the higher the boiling point for the substance.

Why fluorine has low boiling point?

Fluorine is the most abundant halogen in the earth along with chlorine. It is always found in a compound. It has a low melting point and boiling point, the lowest of the halogens. This is because the instantaneous dipole-induced dipole bonds are weak due to F2 having less electrons than any other halogen molecules.

What is boiling point of F2?

-306.4°F (-188°C)
Difluorine/Boiling point

Does F2 have a higher boiling point than Cl2?

Higher boiling points will correspond to stronger intermolecular forces. Correspondingly, I2 will have the highest boiling point and F2 will have the lowest boiling point. Answer: F2, Cl2, Br2, I2. Which substance has the highest/lowest melting/boiling point, etc.

Why are the boiling point of fluorine low?

What is the boiling point of F2?

Why does F2 have a low melting point?

Higher boiling points will correspond to stronger intermolecular forces. Bigger molecules will have stronger London dispersion forces. So I2 has the strongest forces, and F2 will have the weakest.
