Concept explainers
(a)
Interpretation:
For the given ion, all the resonance structures are to be drawn.
Concept introduction:
If a molecule or ion has one of the following features, another resonance structure will exist:
- A lone pair on an atom adjacent to a multiple bond
- An atom with incomplete octet next to a multiple bond or next to an atom with one or more lone pairs.
- Alternating double/triple and single bonds.
The movement of an electron pair is shown with a curved arrow, starting at the pair and ending on the atom or region where it moves. The movement must be from a relatively electron rich atom or region to a relatively electron deficient atom or region.

- Please draw a more stable resonance structure for the following molecule. Use a curved arrow to show how to transform the original structure to the new one and please specify charges.arrow_forwardPlease draw all possible resonance structures, provided with an explanationarrow_forwardProblem Draw Lewis structures for the following:(a) Ethylene (C2H4), the most important reactant in the manufacture of polymers(b) Nitrogen (N2), the most abundant atmospheric gasPlan We show the structure resulting from steps 1 to 4: placing the atoms, counting the total valence electrons, making single bonds, and distributing the remaining valence electrons in pairs to attain octets. Then we continue with step 5, if needed.arrow_forward
- Please answer question in pic. Don’t forgot to add formal charge if it has it in the problemarrow_forwardThe molecule shown here has quite a large dipole, as indicated in its electrostatic potential map. Explain why.Hint: Consider various resonance structures.arrow_forwardDraw a more stable resonance structure for the following molecule. Use a curved arrow to show how to transform the original structure to the new one and please specify charges.arrow_forward
- Draw the major resonance structure for the compound shown; include lone pairs of electrons, formal charges, and condensed hydrogen atoms (located in the More menu). Then draw curved arrows to show how this can be converted to the Lewis structure givenarrow_forwardDraw all reasonable resonance structures for the following compounds. Be sure to show the proper arrows to indicate electron movementarrow_forwardExpand the following condensed formula so as to show all of the bonds and all of the unshared electron pairsarrow_forward
- The next part of the problem is to draw the resonance hybrid. (Exclude formal charges) I’m not sure where to put the dotted resonance lines of the hybrid structure.arrow_forwardDraw all the reasonable resonance structures for the following which delocalizes the negative charge on different atoms. You must use electron pushing arrows notation to show the conversion of a resonance structure into another for full credit.arrow_forwardWrite resonance structure for each of the following compounds and formal charges where appropriate. Which one most to hybrid? Explain.arrow_forward
