Concept explainers
(a)
Interpretation:
The curved arrow pattern should be drawn for the showing the movement of electrons as one resonance contributor is converted to the next.
Concept introduction:
Radical or free radical: unpaired valence electron of an atom, molecule, or ion is called as radical.
(b)
Interpretation:
The curved arrow pattern should be drawn for the showing the movement of electrons as one resonance contributor is converted to the next.

- Use curved arrows to show the most likely acid-base reaction between phenol and NaOH. a. Use pKa data to mark each curved arrow with a positive or negative energy change in pKa ,units. b. Calculate H for this reaction, and sketch an energy diagram showing H as an arrow onyour diagram.arrow_forwardPairs of unshared electrons can be pushed. One Lewis structure for the methoxy-methyl cation is . The structure contains a pair of pushable electrons, namely, the unshared electrons on the atom. The structure also contains a positively charged atom that can act as a . A second resonance structure can be generated by pushing the unshared electrons to the receptor. Thus, It is not possible to push electrons toward the other carbon, because it is not a receptor. If you tried to push electrons to this carbon, you would generate a pentavalent carbon, which is not possible.arrow_forwardAdd curved arrows to show how the first resonance structure can be converted to the second.arrow_forward
- For each example, specify whether the two structures are resonance contributors to the same resonance hybrid.arrow_forwardDraw the resonance interaction.arrow_forwardDraw the resonance structures for the following compound and circle the one that contributes most to the resonance hybrid. Why?arrow_forward
- Draw additional resonance structures for each anion.arrow_forwardAdd arrows to indicate the movement of electrons in going from the central resonance structure to the other significant contributor.arrow_forwardDescribe with words how you would draw the curved arrow(s) to get to the more stable resonance form for the left-hand pair. Be sure to include how many curved arrows are needed and what atom (or bond) the electrons are coming from or going to. Do the same for the resonance pair on the right-hand side. more stable more stablearrow_forward
