Question
Chapter 8, Problem 65GQ
Interpretation Introduction
Interpretation:
The Lewis structure and resonance structure of the given three species should be drawn and the differences and similarities of these three species should be identified.
Concept Introduction:
- Lewis structures are diagrams that represent the
chemical bonding of covalently bonded molecules and coordination compounds. - It is also known as Lewis dot structures which represent the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule.
- The Lewis structure is based on the concept of the octet rule so that the electrons shared in each atom should have 8 electrons in its outer shell.
- Sometimes the chemical bonding of a molecule cannot be represented using a single Lewis structure. In these cases, the chemical bonding are described by delocalization of electrons and is known as resonance.
- All the possible resonance structures are imaginary whereas the resonance hybrid is real.
- These structures will differ only in the arrangement of the electrons not in the relative position of the atomic nuclei.

HSO3(aq) + O3(aq) → HSO4 (aq) + O₂(8)
A solution is prepared in which the initial concentration of HSO₂ (aq) (6.4 × 10+ M) is much larger than that
of O3(aq) (1.0 × 10-5 M). The concentration of O3(aq) is monitored as the reaction proceeds, and the data
are plotted in the graph below.
