Concept explainers
(a)
Interpretation:
The effect of increased strength of intermolecular forces on boiling point of liquids has to be determined.
Concept Introduction:
Dipole-dipole interactions come into play when partial charges of different dipoles interact with each other. Higher polarity between molecules more will be dipole-dipole interactions between them and vice-versa. Boiling point is governed by strength of dipole-dipole interactions that is measured in terms of dipole moments. Boiling point is directly related to dipole moment of molecules. More dipole moment of molecules, higher will be boiling point and vice-versa.
(b)
Interpretation:
The effect of increased strength of intermolecular forces on viscosity of liquids has to be determined.
Concept Introduction:
Viscosity is a characteristic property of liquid particles that allows resistance to their flow. In other words, it represents opposition to flow of liquids.
(c)
Interpretation:
The effect of increased strength of intermolecular forces on surface tension of liquids has to be determined.
Concept Introduction:
Refer to part (a).

- (a) Explain their differences in viscosity in terms of the size and shape of their molecules and their IMFs. The (weaker)(stronger) the intermolecular forces, the higher the viscosity. Ethylene glycol and ethanol both exhibit hydrogen bonding, but since ethylene glycol contains (more)(fewer) opportunities for hydrogen bonding than ethanol, its viscosity is higher. Acetone has a lower viscosity than ethanol since its dipole-dipole force is (weaker)(stronger) than hydrogen bonding. Diethyl ether has a lower viscosity than acetone since it is (more)(less) polar than acetone. (b) Explain their differences in surface tension in terms of the size and shape of their molecules and their IMFs. The (weaker)(stronger) the intermolecular forces, the higher the surface tension. Ethylene glycol and ethanol both exhibit hydrogen bonding, but since ethylene glycol contains (more)(less) opportunities for hydrogen bonding than ethanol, its surface tension is higher.
