Concept explainers
Interpretation: The Lewis structure of below
Concept introduction: Lewis structure is representation of molecule in which dots are shown to represent unshared electrons and lines are shown to represent bonds. These lines and dots represent distribution of electrons in the molecule.
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.

Organic Chemistry: A Guided Inquiry
- In the following Lewis structure of [(CH3)2OH]*, 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). H.

- 3. For each molecule below, draw two additional resonance reasonable structures. Be show sure to show how the resonance structures are related using formal arrow pushing. Rank the resonance structures from most stable to least stable (if they are the same stability rank them the same). Finally, draw the hybrid.
