Question

the boiling point C6H6 CH3OH ,C6H5NH2 and C6H5NO2 are 80°C ,65°C ,184°C and 212°C respectively which of the following will have highest vapour pressure at room temperature​

Answer 1

Answer:

CH₃OH will have highest vapor pressure at room temperature.

Explanation:

If the vapor pressure is high than molecules easily escape from the surface because they require little amount of heat to break the inter molecular forces because of high vapor pressure thus boiling occur at low temperature.

This vapor pressure and boiling point are inversely related to each other.

In given list the lowest boiling point is 65°C which means CH₃OH have highest vapor pressure.

while C₆H₅NO₂ have lowest vapor pressure because of highest boiling point.

Answer 2

Answer:CH3OH

Explanation:because Boiling point is inversely proportional to vapour pressure

so which have low boiling point , have high vapour pressure ....
