(a)
Interpretation:
The type(s) of intermolecular forces existing in between the molecules of the given compounds have to be identified.
Concept Introduction:
Intermolecular forces are the forces existing between molecules, atoms, ions or dipoles.
Depending upon the type of species involved, the intermolecular forces can be classified as follows:
- Dipole-Dipole interactions.
- Ion-Dipole interactions.
- Dipole-induced dipole interactions.
- Ion-induced dipole interactions.
- Dispersion forces.
- Hydrogen bonding.
- Dipole-Dipole interaction is the interaction between two polar molecules which have net dipole moments.
- Ion-Dipole interaction is the interaction between an ionic species (such as cation or anion) and a polar molecule.
- Dipole-induced dipole is the interaction between an atom (non- polar species) and a polar molecule. In this interaction, a polar molecule induces its dipole moment to a non-polar species which lacks dipole moment.
- Ion-induced dipole interaction is the interaction between an atom (non- polar species) and an ionic species. In this interaction, an ionic species such as cation or anion, induces dipole in a non-polar species which lacks dipole moment.
- Dispersion force is the interaction between non-polar molecules.
- Hydrogen bonding can also be defined as coulombic attraction between the hydrogen atom and an electronegative atom. It is a special type of Dipole-Dipole interaction.

- 6. Ethanoic acid (CH3COOH) has a much lower vapor pressure than ethanol (CH3CH2OH). What is the most reasonable explanation? (A) The polarizability of two oxygen atoms increases the London forces of attraction in ethanoic acid compared with ethanol. (B) Hydrogen bonding in ethanoic acid is the strongest attractive force and is mainly responsible for the observed data. (C) Both ethanol and ethanoic acid have an – OH, so the difference is the dipole of the second oxygen that increases the attractive forces. (D) Ethanol has an - OH group and can hydrogen bond; therefore, the London forces must cause the effect.arrow_forwardName the type(s) of intermolecular forces that exists between molecules (or basic units) in each of the following species: (a) NaCL (b) CS2arrow_forward10.
