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 alcohol does; it has a stronger dipole difference in its -OH group.
It s the structure and bonding of Aniline, Phenol, Benzene and Toluene that causes the differences in the boiling points.
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.
The boiling point of methyl alcohol (methanol) is 64.7oC.
The boiling point of alcohol is 173F/78C. Similarly the boiling point of pure water is 212F/100C. Hence the mixing of water and alcohol will have a boiling point that lies between these two ratios.

Because the boiling point of alcohol is lower than the boiling point of water.
A given form of liquid alcohol will turn to vapor at its boiling point, which is different for each type of alcohol.
The boiling point for alcohol depends on the type of alcohol. For ethanol or grain alcohol it is 173.1 F and for isopropyl alcohol 177 F.
The boiling point of methyl alcohol (methanol) is 64.7oC.
Ethyl alcohol, also known as ethanol, has a boiling point of 78.37
The boiling point of alcohol is 173F/78C. Similarly the boiling point of pure water is 212F/100C. Hence the mixing of water and alcohol will have a boiling point that lies between these two ratios.
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.
The boiling point is not changed.
