Question
Chapter 5, Problem 35CTQ
Interpretation Introduction
Interpretation: Any one structure from top row is enough to describe the molecule in top row but all structure is needed from bottom row to describe the molecule in bottom row should be explained.
Concept introduction: When one single structure is unable to describe all the properties of single molecule, a phenomenon called resonance comes into play. This arises when two or more than two Lewis structures are possible for one molecule. All such structures are called resonating structures and have same placement of atoms in them but these have different locations of bond pairs and lone pairs. The resonating structures are inter-convertible with each other. The resultant of all the resonating or contributing structures is called the resonance hybrid.
Rules to form resonance structure are as follows:
1. Use arrow types 1 and 2 for resonance structure of anions in movement of negative charge.
2. Use only arrow type 3 to move a positive charge for resonance structure of cations.
3. The sigma bond should not be broken. Any atom must not move from its place and total number of electrons must be same in all resonance structures.

A resonance hybrid is a structure that can be depicted by more than one valid Lewis structure.
part1: Draw the major resonance form of fulminic acid, HCNO, with the atoms connected as indicated in the formula. Your structure should have nonzero formal charges minimized, and it should include all nonzero formal charges and all nonbonding electrons.
part2: Draw the second most important resonance form of fulminic acid, HCNO, with the atoms connected as indicated in the formula. Your structure should have nonzero formal charges minimized, and it should include all nonzero formal charges and all nonbonding electrons.
part3: Draw the least important resonance contributor for fulminic acid, HCNO, with the atoms connected as indicated in the formula. Your structure should have nonzero formal charges minimized and should include all nonzero formal charges and all nonbonding electrons.
In the following Lewis structure of [SiF6]², every atom, bond and lone pair is positioned. To complete the structure, drag the formal
charge tags to the appropriate atom(s). Each marker may be used more than once, or not at all. If an atom has a formal charge of
zero, do not drag a tag to it.
When you drag the marker in, place the little crosshairs in the upper left corner of the marker directly over the atom(s) in
question (not above them).

You must show your work as to how the structure was drawn including showing valence electrons, any structures you draw that don’t work and require you to show a multiple bond, and formal charges on each atom that has a formal charge. For example, Nitrate ion has three structures (but you can’t draw this one). All three structures have formal charges and no one structure is preferred based on formal charge. Carbon dioxide would not be a valid choice. While it does have three structures, the structure that has two double bonds is the preferred structure while the structures with triple bonds are not equivalent to the double bonded version as they have multiple formal charges present.arrow_forwardDraw a complete Lewis structure for histidine in which all atoms have a formal charge of zero.arrow_forward
