Examples of volatile liquids?
A Volatile liquid is any liquid that can be vaporised quickly. This does not mean they are necessarily flammable. Examples - Water Chloroform Hexane Acetone Petrol methylated spirits alcohol..........
Which evaporates faster alcohol or ether?
There are two reasons for this; {1} boiling point: Tthe boiling point of water is greater than that of ether. So when the boiling point is greater then the vapour pressure will be low. {2} intermolecular forces: The second is intermolecular forces. When intermolecular forces are greater then the the boiling point will be greater and if boiling point is greater then the vapor pressure will be low. The inter molecular forces of water is greater than that of ether and so the vapour pressure will be low and and boiling point will be greater.
Is benzene or ethyl ether highly volatile?
Ethyl ether is more volatile than benzene. Ethyl ether has a lower boiling point and vapor pressure, making it easier for it to evaporate rapidly. Benzene is less volatile compared to ethyl ether due to its higher boiling point and lower vapor pressure.
Ether at room temperature is placed in a flask connected by a rubber tube to a vacuum pump the pump is turned on and the ether begins to boil why?
Because the pressure of the atmosphere in the flask is lowered by the vacuum; a liquid will reach it's boiling point when the pressure of the atmosphere is equal to or less than the vapor pressure of the liquid.
Can boiling point of acetone be lowered if placed in a vacuum?
Yes, the boiling point of acetone can be lowered if placed in a vacuum, as reducing the pressure lowers the boiling point of a substance. This is because at lower pressure, there is less external pressure pushing down on the liquid molecules, allowing them to escape into the vapor phase more easily.
Does vapour pressure depend upon the nature of a liquid?
Yes, the vapor pressure of a liquid depends on the nature of the liquid. Factors such as temperature, intermolecular forces, and molecular weight influence the vapor pressure of a liquid. Lower intermolecular forces and higher temperatures lead to higher vapor pressure.
Why vapour pressures of solids are far less than those of liquids?
The vapour pressure of solids are far less than those of liquid because solids have fixed arrangement of molecules and between atom of solids their is strong intermolecular forces that held the molecules in place and the molecules of liquid have less intermolecular forces as compared to solids.
Why does acetone evaporate so fast?
Acetone evaporates faster than alcohol and water because alcohol and water contain intermolecular hydrogen bonding but acetone does not. This is the reason alcohol and water have higher boiling point than acetone and evaporate slower than it.
Do water vapour has volume?
But of course the vapour of the water have the volume. but it is a less than the water itself goodbye.
Why the vapour pressure of solids are far less than those of liquids?
The vapour pressure of solids are far less than those of liquid because solids have fixed arrangement of molecules and between atom of solids their is strong intermolecular forces that held the molecules in place and the molecules of liquid have less intermolecular forces as compared to solids.
Can acetone be used in recrystallization?
Yes. One method used allows dissolving your compound in a mix of acetone and toluene for instance. as the acetone evaporates, the mix becomes less polar and the compound recrystallises.
What are the differences between isopropyl and acetone, and how do they compare in terms of their uses and properties?
Isopropyl and acetone are both solvents, but they have different chemical structures. Isopropyl alcohol is a type of alcohol, while acetone is a type of ketone. Isopropyl alcohol is commonly used as a disinfectant and cleaning agent, while acetone is often used as a solvent for paints and nail polish. Isopropyl alcohol is less volatile and less flammable compared to acetone.
