Why bromine has higher boiling point than chlorine?

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 chlorine have a low boiling points?

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.

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.

Why is the boiling point of chlorine lower than iodine?

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.

Does chlorine have a high boiling point?

-29.27°F (-34.04°C)
Chlorine/Boiling point

What is the boiling point of chlorine?

What is boiling point of bromine?

137.8°F (58.8°C)
Bromine/Boiling point

Why water has higher boiling point than bromine?

It has a greater molar mass and therefore exhibits stronger dispersion forces than bromine. As the size of the halogens increases, the melting and boiling points increase. The energy required to move and separate the molecules from one another increases as the size of the molecules increases.

Is bromine less reactive than chlorine?

Because chlorine is more reactive than bromine, it displaces bromine from sodium bromide.

Why bromine is less reactive but more selective than chlorine?

Bromination of alkanes occurs by a similar mechanism, but is slower and more selective because a bromine atom is a less reactive hydrogen abstraction agent than a chlorine atom, as reflected by the higher bond energy of H-Cl than H-Br.

What’s the melting point and boiling point of chlorine?

chlorine

atomic number	17
melting point	−103 °C (−153 °F)
boiling point	−34 °C (−29 °F)
density (1 atm, 0 °C or 32 °F)	3.214 g/litre (0.429 ounce/gallon)
oxidation states	−1, +1, +3, +5, +7

What is the difference between bromine and 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 bromine have a high boiling point?

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. Therefore, bromine is larger and has stronger intermolecular forces, meaning it requires more heat energy to break the strong bonds (high boiling point).

Why do fluorine and chlorine have low boiling and melting points?

These exist as diatomic molecules where the two atoms are joined by a single covalent bond. As low molecular weight covalent molecules they would be expected to have low boiling and melting points and, indeed, fluorine and chlorine are gases at room temperature, whereas bromine is a volatile liquid and iodine is a volatile solid.

Why does Cl2 have a low boiling point?

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. 8 clever moves when you have $1,000 in the bank.
