Question
Chapter 8.9, Problem 1PPA
Interpretation Introduction
Interpretation:
The best arrangement for the carboxyl group with respect to its formal charge is to be determined.
Concept introduction:
For many molecules, it is impossible to explain all properties by a single Lewis structure. In such cases, more than one Lewis structures are drawn to explain the properties. Such structures of a compound are called resonating structures and the phenomenon is called resonance.
Due to their attraction towards electrons, ions and molecules acquire some charge which is called formal charge.
Formal charge is given by:
Total number of valence electrons in a free

Resonance Forms
Question (b) Draw two resonance forms for nitrite ion, NO2−. What can yousay about the geometry of this molecule (linear or bent)?
(Hint: Consider the effect of electron repulsion exerted by the lone pair on nitrogen.)
(c) The possibility of valence-shell expansion increases the number of feasibleresonance forms, and it is often difficult to decide on one that is “best.” Onecriterion that is used is whether the Lewis structure predicts bond lengths andbond angles with reasonable accuracy. Draw Lewis octet and valence-shellexpanded resonance forms for SO2(OSO).
Considering the Lewis structure for SO (Exercise 1-8), its experimental bond length of1.48Å, and the measured S–O distance in SO2 of 1.43Å, which one of the various structures would you consider “best”.
Explain your answer in depth, clarity and with details and in a step-by-step fashion.

- Learning Goal: To use electronegativity or metal versus nonmetal classifications to distinguish covalent, polar covalent, and ionic bonds. When two bonded atoms attract electrons with equal strength, the result is a nonpolar covalent bond. A polar covalent bond is one in which the electrons are unequally shared between the atoms. An ionic bond results when the sharing is so unequal that fully charged ions form. Electronegativity difference can be used to predict bond type. If electronegativities differ by more than 2 units, the bond is substantially ionic; if they differ by less than 2 units, the bond is polar covalent; and if the values are equal, the bond is nonpolar covalent. If you are not given electronegativity values, you can still predict the bond type using the periodic table. Metals have low electronegativity compared to nonmetals. So in general, we can predict that ary metal-nonmetal combination will be ionic and any nonmetal-nonmetal combination will be covalent. If…arrow_forwardA) Which of the following bonds are nonpolar?
