Question: Why Is The Boiling Point Of Water Higher Than The Boiling Point Of Chlorine?

Why does chlorine have a high boiling point?

Why does chlorine have a higher boiling point than hydrogen chloride.

Chlorine has a boiling point of 238 K while hydrogen chloride has a boiling point of 188 K.

Hydrogen chloride has dipole-dipole forces so I would expect it to have greater inter-molecular forces and thus a higher boiling point..

What increases boiling point?

The relative strength of the four intermolecular forces is: Ionic > Hydrogen bonding > dipole dipole > Van der Waals dispersion forces. The influence of each of these attractive forces will depend on the functional groups present. Boiling points increase as the number of carbons is increased.

Does water have a high boiling point?

100 °CWater/Boiling pointA liquid at high pressure has a higher boiling point than when that liquid is at atmospheric pressure. For example, water boils at 100 °C (212 °F) at sea level, but at 93.4 °C (200.1 °F) at 1,905 metres (6,250 ft) altitude. For a given pressure, different liquids will boil at different temperatures.

Why bromine has higher boiling point than chlorine?

Chlorine, as chlorine has fewer electrons shells than bromine. As a result, chlorine is smaller and has a smaller atomic radius. … Therefore, bromine is larger and has stronger intermolecular forces, meaning it requires more heat energy to break the strong bonds (high boiling point).

What affects boiling point of water?

For example, for water, the boiling point is 100ºC at a pressure of 1 atm. The boiling point of a liquid depends on temperature, atmospheric pressure, and the vapor pressure of the liquid. When the atmospheric pressure is equal to the vapor pressure of the liquid, boiling will begin.

What happens to h2o when boiled?

When water is boiled, it undergoes a physical change, not a chemical change. The molecules of water don’t break apart into hydrogen and oxygen. Instead, the bonds between molecules of water break, allowing them to change physically from a liquid to a gas. … The gaseous form is water vapor.

What does negative boiling point mean?

I’d appreciate if someone could just explain me the whole thing. Like if both the melting and boiling points are in the negative is the substance considered to be a solid, liquid or gas. Likewise if a substance has a melting point of 0 and boiling point 108 or 110 is it a solid liquid or gas.

Why is the boiling point of water higher than expected?

No bonds in between atoms are broken, just the bonds in between water molecules, in this case hydrogen bonding. … Hydrogen bonding is one of the most powerful intermolecular forces, which is why water has such a high boiling point.

Does chlorine have a high boiling point?

-34.04 °CChlorine/Boiling point

What is the reason for Chlorines low 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). So in conclusion chlorine has a lower boiling point.

Why do melting and boiling points increase down Group 7?

Melting and Boiling Points (increases down the group) 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.

Is chlorine a good conductor?

Chlorine is an element in the third period of the Periodic Table. It is a non-metallic element as are phosphorus and sulfur. … The element chlorine cannot conduct electricity because its outer electrons do not have the ability to move, to work as a conductor, because they have strong covalent bonds.
