Question
Chapter 2.1A, Problem 2.1P
(a)
Interpretation Introduction
To determine: The amount of charge separation in the given
Interpretation: The amount of charge separation in the given
Concept introduction: The polarity of an individual bond is measured as its bond dipole moment. A quantity that describes two opposite charges separated by a distance is the dipole moment. The dipole moment is calculated by the formula,
(b)
Interpretation Introduction
To determine: The relative importance of the given two resonance contributors.
Interpretation: The relative importance of the given two resonance contributors is to be evaluated.
Concept introduction: The delocalization of electrons due to the presence of lone pair of electrons and double bond is called resonance. The resonance structure is more stable if there are more resonating structures. In resonance forms of any compound, the connectivity of atoms is same but the distribution of electrons is different. Resonance helps to explain the structure and reactivity of organic molecules.

On 6b, why are the two Br on the 2nd carbon and not the 3rd??
Compare these two structures.
[0=C=N] [0=C—N:
Determine whether the two represent resonance contributors of a single species or depict different substances. If two structures are not resonance contributors,
explain why. Select the single best answer.
O The two structures are resonance contributors of the same species.
The two structures are not resonance contributors because they contain different numbers of electrons.
The two structures are not resonance contributors because they contain different bond orders.
O The two structures are not resonance contributors because they contain bond orders having integer values.
The two structures are not resonance contributors because each structure is present in its most stable (lowest
energy) configuration.
The two structures are not resonance contributors because they have different arrangements of atoms.
