Why does Cl2 have a higher boiling point than argon?

Chlorine, Cl2, is a much smaller molecule with comparatively weak van der Waals attractions, and so chlorine will have a lower melting and boiling point than sulphur or phosphorus. Argon molecules are just single argon atoms, Ar.

Why would you expect Cl2 to have a higher boiling point than F2?

Larger size means there are more electrons available to form the dipoles. Cl is lower on the Table. It has 3 energy levels while F has only 2 energy levels. So Cl2 is larger than F2.

Why does argon have a high boiling point?

Argon has larger mass than helium and has larger dispersion forces. Because of larger size, the outer electrons are less tightly held in the larger atoms so that instantaneous dipoles are more easily induced resulting in greater interaction between argon atoms. Therefore, the boiling point of Aris more than that of He.

Which of the following has the highest boiling point F2 Cl2 br2 i2?

2. Look for molecules with dipoles. These will have the next strongest intermolecular forces. Higher surface tension corresponds to stronger intermolecular forces.

Why does F2 and argon have similar boiling points?

Its boiling point is very similar argon despite the greater spread of electron charge over both atoms of the diatomic molecule.

Does F2 have a higher boiling point than HCl?

F2 has van der Waals’ forces, whilst HCl has permanent dipole–dipole attractions. Permanent dipole–dipole attractions are much stronger than induced dipoles. More enegery is required to break the stronger permanent dipole–dipole attractions, and therefore HCL has a higher boiling point.

Why does Br2 have a high boiling point than Cl2?

Br2 molecules are larger than Cl2 molecules, so more electrons are present in Br2 molecules. Therefore there are stronger van der waals forces between Br2 molecules than Cl2 molecules, so more energy is needed to melt Br2.

Why argon has low boiling point?

Argon is monatomic – it exists as separate atoms. There are are van der Waals’ forces between its atoms. The melting and boiling points of these elements are very low because: van der Waals’ forces are very weak forces of attraction …

Does argon have the highest boiling point?

Argon will have the higher boiling point because it has a larger molar mass than helium. As the molar mass of an element increases, the boiling…

Why does Cl2 have a higher boiling point than Br2?

Why does Br2 have a higher boiling point than F2?

The boiling points in F2, Cl2, Br2 and I2are determined by the size of the dispersion forces between molecules. The bigger the atoms, the more polarisable their electron clouds and the greater the dispersion forces. Hence boiling points are in order: I2 > Br2 > Cl2 > F2.
