I 2 has a higher boiling point than Br 2 . The atomic weights of Br and I are 80 and 127 respectively. Since I 2 has higher molecular weight, it has stronger London dispersion forces
Does Br2 or I2 have greater dispersion forces?
Bigger molecules will have stronger London dispersion forces. So I2 has the strongest forces , and F2 will have the weakest. Correspondingly, I2 will have the highest boiling point and F2 will have the lowest boiling point.
What has a higher melting point Br2 or I2?
Since I2 has higher molecular weight, it has stronger London dispersion forces so it has a higher boiling point than Br2.
Which has higher vapor pressure Br2 or I2?
CH3CH2Cl, therefore, the compound with this highest energy intermolecular interaction will take the longest to boil. For the following pair of compounds, pick the one with the higher vapor pressure at a given temperature: Br2 or I2 . The lower the molar mass, the higher the vapor pressure. Br2 has a lower molar mass.
Which is stronger Br2 or 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.
Which is stronger I2 or Br2?
I2 has a higher boiling point than Br2. The atomic weights of Br and I are 80 and 127 respectively. Since I2 has higher molecular weight, it has stronger London dispersion forces
Why I2 has higher boiling point than Br2?
Iodine has a higher boiling point than bromine because it has a higher relative molecular mass and so more electrons than Br2 , so there are stronger van der Waals’ forces of attraction between the molecules. More energy is needed to break these and so iodine has a higher boiling point than bromine.
What is the strongest intermolecular force?
The Ion-dipole force is the strongest imf. Occurs when a polar molecule (molecule with a dipole) comes in contact with an ion.
Is I2 more polarizable than Br2?
Since I 2 has higher molecular weight, it has stronger London dispersion forces so it has a higher boiling point than Br 2 .
Which has higher boiling point Xe or I2?
HCl has a lower boiling point because its dipole-dipole forces are weaker than the ionic bonds present in LiCl. ... Xe and I2 are both nonpolar and thus have London forces only. But Xe’s dispersion forces are weaker because it is smaller and therefore less polarizable compared to I2.
Why I2 is solid and Br2 is liquid?
As we move from fluorine to iodine, the electrons are further from the nuclei so the electron clouds can more easily distort. The London dispersion forces
Which molecule will have the strongest attraction to another molecule of its own kind?
Dipole-dipole interactions are the strongest intermolecular force
Why do melting points increase down Group 17?
The melting and boiling points increase down the group because of the van der Waals forces . The size of the molecules increases down the group. This increase in size means an increase in the strength of the van der Waals forces.
Why Br2 has a high boiling point?
In short “ The more electrons a molecule has , the stronger the London dispersion forces
Which of these has the strongest London dispersion forces?
The dispersion forces are strongest for iodine molecules because they have the greatest number of electrons.
Which has the highest boiling point I2 Br2 and Cl2 explain why?
In short “The more electrons a molecule has, the stronger the London dispersion forces
