Question

The boiling point of benzene ,methanol,C6H5NH2 and C6H5NO2 are 80 degree celcius ,65℃ ,184℃ and212℃ respectively which will show highest vapour pressure at riom temperature

Answer 1

Answer:

Methanol has the highest vapour pressure at room temperature because of the least boiling point, which indicates the least strength of intermolecular forces of attraction.

Answer 2

At room temperature, methanol will show highest vapor pressure at room temperature.

Explanation:

Boiling point is the temperature at which vapor pressure of a liquid becomes equal to the atmospheric pressure. This means that weaker is the intermolecular forces present within a molecule or compound lesser will be its vapor pressure.

This means that a compound with low boiling point will also have low vapor pressure. This is also due to weak interactions present within the molecules of a compound.
