Concept explainers
a)
Interpretation:
- The resonance contributors for the given compound has 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.
b)

- Use curved arrows and draw four additional resonance contributors. Please circle the most significant contributor(s) to the resonance hybird and explain why.arrow_forwardFor each molecule below, draw the conjugate acid or conjugate base or both if the molecule hasboth a conjugate acid and a conjugate base (e.g., water).arrow_forwardConsider the following bases: a. For each base above, circle the atom/atoms with the highest PE (will release the most P.E.when a lone pair on this atom combines with an H+ ) b. Rank the bases 1 (highest P.E./strongest base) to 7 (lowest PE/weakest base), and explainyour reasoning.arrow_forward
- Summarize the relationship between pKa and acid strength by completing the following sentences: a. The higher the pKa of an acid, the stronger or weaker the acid. b. The lower the pKa of an acid, the stronger or weaker the acid.arrow_forward2. Use curved arrows to show electron movement in the reactant side and draw the product/s of the Lewis acid-base (nucleophile-electrophile) reaction. Label the nucleophile and the electrophile. Draw in all lone pairs and charges where appropriate. Iarrow_forwardGive typed full explanation draw all possible resonance structures and circle the most stable onearrow_forward
- Classify each reaction as either a proton transfer reaction, or a reaction of a nucleophile with an electrophile. Use curved arrows to show how the electron pairs move.arrow_forwarda) Draw the product(s) of the acid/base reaction. b) Will the equilibrium lie left or right?arrow_forwardDraw all contributing resonance structures for the molecule shown below.
