Lewis formulas are misleading in the sense that atoms and electrons are shown as being static. But we know that a given compound can have several valid Lewis formulas. For example CH3CNO can be represented by at least three different Lewis structures called resonance forms, or resonance structures: C C N O.
Practice on Resonance Structures - Answers. 1. For each of the following draw reasonable resonance structures. 2. Draw reasonable resonance structures for each of the following molecular structures.
Mrs. Meer. Organic Chemistry. Name_______________________________. Date_____________ Period ______. Even More Resonance Practice Problems. Draw all of the reasonable resonance structures for each of the following molecules. a. O. H2N.
Resonance Practice Worksheet. LANEY COLLEGE INSTRUCTOR: S. CORLETT. On a separate sheet of paper, rewrite each of the structures below, including all lone pairs of electrons (all are shown, so don’t add any). Then use electron pushing to show all other resonance forms. If there is a major form, then circle it.
The following is a collection of ions and neutral molecules for which several resonance structures can be drawn. For the ions, the charges can be delocalized implying greater stability; for the neutral molecules, electrons can be shuffled around to show areas of high or low electron density.
In the resonance forms shown above the atoms remain in one place. The basic bonding pattern, or connectivity, is the same in all structures, but some electrons have changed locations. This means that there are certain rules for electron mobility that enable us to “push” electrons around to arrive from one resonance structure to another.
