There are a huge number of alcohols - each with its own boiling point when pure. There is, therefore, no simple answer.
The boiling point of pure ethanol is 78,37 0C.
The pure ethanol has the boiling point 78.5 celsius while water has 100 celsius so when water is added to ethanol its boiling point becomes increased.
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.
All pure liquids, such as water, H20, have constant boiling points at certain atmospheric pressures, which is helpful in determining the identity of an unknown liquid. Some liquids have constant boiling points that are not pure, such as nail polish remover, or ethyl acetate. Since it is a mixture of more than one pure liquid, it is not a pure liquid itself, but if always mixed in the same ratios, will have a constant boiling point.
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 pure ethanol is 78,37 0C.
The pure ethanol has the boiling point 78.5 celsius while water has 100 celsius so when water is added to ethanol its boiling point becomes increased.
At Boiling Point all the material evaporates leaving no residue which means it is pure. But if it leaves some residue after evaporating at boiling point then it is not pure. For example : If you take an example of pure water & Saline Water then pure water will evaporate at its boiling point leaving nothing after it. But Saline water evaporates leaves salt behind it.

Boiling Point Elevation
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.

The boiling point of methyl alcohol (methanol) is 64.7oC.
pure substances have a distinct boiling point. Adding more heat just makes the substance boil faster but the temperature stays the same. A mixture does not have a distinct boiling point. Adding more heat will make the temperature increase.
