Which has higher boiling point Br2 or ICl?
ICl exhibits Keesom forces and Debye forces while Br2 does not, and these additional intermolecular forces can explain the higher boiling point of ICl.
Why does CL have a higher boiling point than Br?
Since bromine has larger size than chlorine, it will have stronger intermolecular forces and so more heat energy is required to break the strong bonds. Thus, bromine has a higher boiling point than chlorine. Dispersion forces are displayed more strongly by larger and heavier atoms than smaller and light atoms.
Does Cl2 Br2 or I2 have a higher boiling point?
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.
Why does bromine have a lower boiling point than iodine?
Iodine molecules have a bigger molecular mass and more electrons than that of bromine and thus have a larger polarity. Therefore the bigger the molecular mass and polarity of molecules, the stronger the intermolecular forces resulting in iodine having a higher boiling point.
Why does iodine have a higher boiling point than chlorine?
Iodine is always found in a compound. Its melting and boiling point are higher than fluorine, chlorine or bromine. This is because the instantaneous dipole-induced dipole bonds are stronger (it has more electrons).
Why iodine has higher boiling point?
Iodine is a larger molecule, with more electrons, than chlorine. Therefore Iodine has stronger intermolecular forces than chlorine, which require more energy to break. This results in Iodine having a higher boiling point than chlorine.
Why does I2 have a higher boiling point than Cl2?
Why does iodine have a low melting point a level?
The iodine atoms in the I2 molecule are joined by a single covalent bond – one electron short of a noble gas configuration. Iodine tends to sublime at temperatures approaching 114oC and only melts under pressure, low melting/boiling/sublimation points and low state change enthalpies due to weak intermolecular bonding.
Why does chlorine have a low boiling point a level?
Cl2 is a non-polar molecule. The primary intermolecular force it can share with its nearest neighbors is London dispersion forces, which are short range very weak forces. Thus, the amount of energy needed to get the chlorine to boil is low, so the boiling point is low.
