Which has a higher melting point chlorine or bromine?
Bromine is always found in a compound. It has a low melting point and boiling point although higher than fluorine and chlorine.
Does Br2 or Cl2 have a higher melting point?
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.
Does bromine have a high melting point?
-7.2 °C
Bromine/Melting point
Does chlorine have a higher melting point?
Chlorine: 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 sulfur or phosphorus.
Does chlorine have a high or low melting point?
| Chlorine | |
|---|---|
| Phase at STP | gas |
| Melting point | (Cl2) 171.6 K (−101.5 °C, −150.7 °F) |
| Boiling point | (Cl2) 239.11 K (−34.04 °C, −29.27 °F) |
| Density (at STP) | 3.2 g/L |
Why does melting point 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.
Which molecule has the highest boiling point Br2 Cl2 I2 or 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.
What is the melting point of Br2?
265.8 K
| Bromine | |
|---|---|
| Phase at STP | liquid |
| Melting point | (Br2) 265.8 K (−7.2 °C, 19 °F) |
| Boiling point | (Br2) 332.0 K (58.8 °C, 137.8 °F) |
| Density (near r.t. ) | Br2, liquid: 3.1028 g/cm3 |
Why is bromine boiling point high?
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.
Why does bromine have a high boiling point?
The strength of the intermolecular forces increases with increasing size of the molecule. Therefore, bromine is larger and has stronger intermolecular forces, meaning it requires more heat energy to break the strong bonds (high boiling point).
Why does chlorine have a higher boiling point?
Chlorine, as chlorine has fewer electrons shells than bromine. As a result, chlorine is smaller and has a smaller atomic radius. The difference in size, relates to boiling point of the molecule. This is because the size effects the strength of the forces between the molecules (intermolecular forces).
Why is chlorine melting point so low?
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.
Which has a lower boiling point chlorine or bromine?
Therefore, bromine is larger and has stronger intermolecular forces, meaning it requires more heat energy to break the strong bonds ( high boiling point ). So in conclusion chlorine has a lower boiling point. Need help with Chemistry?
Which is smaller in atomic radius bromine or chlorine?
Chlorine, as chlorine has fewer electrons shells than bromine. As a result, chlorine is smaller and has a smaller atomic radius . The difference in size, relates to boiling point of the molecule. This is because the size effects the strength of the forces between the molecules (intermolecular forces).
Why does boiling point affect the size of a molecule?
The difference in size, relates to boiling point of the molecule. This is because the size effects the strength of the forces between the molecules (intermolecular forces). The strength of the intermolecular forces increases with increasing size of the molecule.
