Concept explainers
(a)
To determine: The diagram that depicts the hydrogen bonding which takes place between two molecules of ethanol.
Interpretation: The diagram that depicts the hydrogen bonding which takes place between two molecules of ethanol is to be drawn.
Concept introduction: Hydrogen bonding is the strongest intermolecular forces present between the substances. A hydrogen atom participates in hydrogen bonding if it is bonded to electronegative atom like fluorine, oxygen or nitrogen. Organic compounds do not contain H−F bonds so only N−H and O−H hydrogen’s are considered to be hydrogen bonded.
(b)
To determine: The diagram that depicts the hydrogen bonding which takes place between two molecules of propylamine.
Interpretation: The diagram that depicts the hydrogen bonding which takes place between two molecules of propylamine is to be drawn.
Concept introduction: Hydrogen bonding is the strongest intermolecular forces present between the substances. A hydrogen atom participates in hydrogen bonding if it is bonded to electronegative atom like fluorine, oxygen or nitrogen. Organic compounds do not contain H−F bonds so only N−H and O−H hydrogen’s are considered to be hydrogen bonded.
(c)
To determine: The diagram that depicts the hydrogen bonding which takes place between a molecule of dimethyl ether and two molecules of water.
Interpretation: The diagram that depicts the hydrogen bonding which takes place between a molecule of dimethyl ether and two molecules of water is to be drawn.
Concept introduction: Hydrogen bonding is the strongest intermolecular forces present between the substances. A hydrogen atom participates in hydrogen bonding if it is bonded to electronegative atom like fluorine, oxygen or nitrogen.

(d)
To determine: The diagram that depicts the hydrogen bonding which takes place between two molecules of trimethylamine and a molecule of water.
Interpretation: The diagram that depicts the hydrogen bonding which takes place between two molecules of trimethylamine and a molecule of water is to be drawn.
Concept introduction: Hydrogen bonding is the strongest intermolecular forces present between the substances.

- b) Certain cyclic compounds are known to be conformationally similar to carbohydrates, although they are not themselves carbohydrates. One example is Compound C shown below, which could be imagined as adopting four possible conformations. In reality, however, only one of these is particularly stable. Circle the conformation you expect to be the most stable, and provide an explanation to justify your choice. For your explanation to be both convincing and correct, it must contain not only words, but also "cartoon" orbital drawings contrasting the four structures.
