Concept explainers
(a)
Interpretation:
The vapour pressure of methyl ethyl ether at
Concept Introduction:
Vapour pressure:
The pressure of the vapour when liquid and vapour are in dynamic equilibrium is called vapour pressure. It increases with increase in temperature. The molecule experiencing stronger intermolecular force of attraction, has lower vapour pressure.
(b)
Interpretation:
The liquid having strongest intermolecular attractions has to be determined.
Concept Introduction:
Refer part (a).
(c)
Interpretation:
The temperature at which benzene has a vapour pressure of
(d)
Interpretation:
The normal boiling point of the given liquids has to be determined.
Concept Introduction:
The temperature at which the vapour pressure of the liquid equals to the atmospheric pressure on the surface of the liquid is known as the boiling point.
