Concept explainers
Interpretation:
- The decreasing order of delocalization energy to be investigated.
Concept Introduction:
Delocalization energy: It is a measure of how much more stable a compound with delocalized electrons is than it would be if its electrons were localized. The greater the number of relatively stable resonance contributors, the greater the delocalization energy.
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.

If the TA is right, draw the product in the drawing area below. If the TA is wrong, just check the box below the drawing area. 1. NaOMe CH3O N. OCH3 ? 2. H3O+arrow_forward
- Complete the reaction in the drawing area below by adding the major products to the right-hand side. If there won't be any products, because nothing will happen under these reaction conditions, check the box under the drawing area instead. Note: if the products contain one or more pairs of enantiomers, don't worry about drawing each enantiomer with dash and wedge bonds. Just draw one molecule to represent each pair of enantiomers, using line bonds at the chiral center. + More... ☐ ☐ : ☐ + G 1. NaOMe Click and drag to start drawing a structure. 2. H +arrow_forward6.
