This is because the intermolecular forces holding the molecules of phenol together are stronger than the intermolecular forces holding the molecules of alcohol together.
Phenol has a higher boiling point than alcohols. This is because phenol molecules can form intermolecular hydrogen bonds due to the presence of the hydroxyl group attached to the aromatic ring, leading to stronger attractive forces between molecules compared to alcohols.
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.
Aniline has a higher boiling point than phenol because aniline can form strong hydrogen bonds due to the presence of an amino group. Phenol has a higher boiling point than toluene because phenol molecules can form intermolecular hydrogen bonds because of the hydroxyl group. Toluene has a higher boiling point than benzene due to the presence of a bulky methyl group which increases Van der Waals forces between toluene molecules.
Water has a higher boiling point that alcohol (ethanol). The main reason for this is because water has stronger intermolecular forces holding the molecules together.
The boiling point of a mixture of alcohol and water depends on the ratio of the two substances. For example, a solution of 20% alcohol and 80% water will have a boiling point higher than either pure alcohol or water. The boiling point elevation is due to the interactions between the alcohol and water molecules.

The boiling point of alcohol can vary depending on the type of alcohol. For example, the boiling point of ethanol (found in alcoholic beverages) is around 78.37°C (173.07°F). Isopropyl alcohol, often used as rubbing alcohol, has a boiling point of around 82.6°C (180.7°F).

The boiling point of alcohol varies depending on the specific type of alcohol. For example, the boiling point of ethanol (drinking alcohol) is around 78.37°C (173.07°F) at standard atmospheric pressure.
A given form of liquid alcohol will turn to vapor at its boiling point, which is different for each type of alcohol.
Water has a higher boiling point that alcohol (ethanol). The main reason for this is because water has stronger intermolecular forces holding the molecules together.
Alcohol thermometers typically have a lower maximum temperature range compared to mercury thermometers, making them unsuitable for measuring the high boiling point of water. Alcohol thermometers may not accurately measure temperatures above their boiling point, which is lower than water's boiling point.

For example, a solution of 20% alcohol and 80% water will have a boiling point higher than either pure alcohol or water. The boiling point elevation is due to the interactions between the alcohol and water molecules.
The boiling point of methyl alcohol (methanol) is 64.7oC.
Ethyl alcohol, also known as ethanol, has a boiling point of 78.37
Any form of liquid alcohol will change to vapor when its temperature reaches the boiling point (different for each type of alcohol).Alcohol (ethyl alcohol) is a volatile liquid and changes in to vapours at every temperature although its boiling point is 78.5 Celsius.
