Concept explainers
- a)
Interpretation:
- The compounds containing delocalized electrons to be identified and resonance contributors for those given compounds to be drawn.
Concept Introduction:
Resonance Contributor: The appropriate structure with the localized electrons is called a resonance contributor, a resonance structure, or a contributing resonance structure.
Delocalized electrons: The sharing of electrons between two or more atoms known as delocalization of electrons. In order to have delocalized electrons, the system must be planar and have alternative double bonds and single bonds.
Resonance hybrid: the actual structure with delocalized electrons is called a resonance hybrid.

- x-xo B Draw molecule A. On that drawing include the lone pairs and the curved arrows that would produce resonance structure B.arrow_forward1. Add nonbonding electron pairs to each atom where it is implied by the line-angle drawings shown below. 2. Use the curved arrow formalism to generate four additional, valid resonance structures for each compound. 3. Rank your resonance structures in order of increasing contribution to the overall nature of the molecule.arrow_forward1. Draw an aromatic ring, which contains only hydrogens and 5 carbons; add charges and lonepairs if needed 2. Draw a non-aromatic ring which contains only hydrogen and 5 carbons and have conjugateddouble bonds; add charges and lone pairs if needed.arrow_forward
- 4. Draw the possible resonance structures for compounds C and D. Include lone pairs and indicate non-zero formal charges. Circle the minor resonance contributor for compound C. O :O: :O: C & Darrow_forwardDraw the resonance structures for the following compound and circle the one that contributes most to the resonance hybrid. Why?arrow_forwardDraw additional resonance structures for each anion.arrow_forward
