(a)
Interpretation: The approximate vapor pressure curve of ethanol at
Concept Introduction: Vapor pressure is nothing but the pressure of a vapor in contact with its liquid or solid form.
When a liquid and vapor are in equilibrium the pressure exerted by the vapor is called the equilibrium vapor pressure.
If intermolecular force is small the vapor pressure of the substance is high and the boiling point will be low.
(b)
Interpretation: It has to be identified whether
Concept Introduction:
Intermolecular force: The attractive force that withholds two molecules is called as intermolecular force. The influence of intermolecular forces depends on molar mass and the
Dipole-Dipole Interactions: The attractive force that holds two polar molecules with help of dipole moment present in them is called as Dipole-Dipole Interactions.
The partial positive charge end of one molecule is attracted to the partial negative charge of a neighboring molecule.
Induced Dipole - Induced Dipole Forces: The attractive force that holds two nonpolar molecules with help of temporary dipole moment present in them is called as induced dipole-induced dipole forces.
(c)
Interpretation: The temperature at which heptane have a vapor pressure of
Concept Introduction:
Boiling point: It is the temperature at which liquid converts to vapor. At boiling point the vapor pressure of liquid and the pressure of the surroundings are equal.
Boiling point: It is the temperature at which liquid converts to vapor. At boiling point the vapor pressure of liquid and the pressure of the surroundings are equal.
(d)
Interpretation: The approximate normal boiling points of each of the given substances have to be determined.
Concept Introduction:
Boiling point: It is the temperature at which liquid converts to vapor. At boiling point the vapor pressure of liquid and the pressure of the surroundings are equal.
