Concept explainers
(a)
Interpretation:
All resonance structures of the given species are to be drawn.
Concept introduction:
The only difference between the two resonance structures is the location of electrons. Therefore, one resonance structure can be obtained from another just by moving the electrons while the atoms should remain on their place.

- Problem Draw a Lewis structure and identify the octet-rule exception for (a) H3PO4 (draw two resonance forms and select the more important); (b) BFCl2.Plan We draw each Lewis structure and examine it for exceptions to the octet rule.(a) The central atom is in Period 3, so it can have more than an octet.(b) The central atom is B, which can have fewer than an octet of electrons.arrow_forwardDraw the curved arrows to show the resonance structure for the following molecules. ( there are 3 molecules )arrow_forward(a) Draw all resonance contributors of the following ion. In drawing each additional resonance structure, use curved arrows to indicate which pairs of electrons are being shifted. (b) Draw the resonance hybrid. (c) Which c–C bond is the longest?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_forwardBelow are two sets of resonance structures. Where applicable provide the missing curved arrow notation, lone pair electrons, and nonzero formal charge. Do not delete or add any bonds or atoms.arrow_forwardWould each end of the bond line structure be carbon? Is problem (a) correct?arrow_forward
- Assign a formal charge to the O atom in the following molecule. All lone pairs have been drawn in. (select) ▼arrow_forward3) Draw two more resonance structures of the following compound. Order the structures by increasing stability.arrow_forwarda) Draw the complete structure of propane. (Draw all hydrogen atoms.) b) Draw the structure of propane in skeleton mode or as a bond-line structure. (Do not draw the hydrogen atoms.)arrow_forward
- Curved arrows are used to illustrate the flow of electrons. Follow the curved arrows and draw the resonance hybrid contributor. Include all lone pairs and charges as appropriate. Drawing Ⓒarrow_forwardAnswer the following true or false questions about the molecule acrylaldehyde, its resonance structures, and resonance hybrid. In fairness, many of these statements are false and represent common misconceptions about resonance. If a statement is false as written, change the underlined fragment of the statement to make it true 4) The pair of electrons labeled “A” (at the end of the arrow) are localized 5) The pair of electrons labeled “B” (at the end of the arrow) are delocalized 6) The pair of electrons labeled “C” (at the end of the arrow) are localizedarrow_forwardGive only typing answer with explanation and conclusion What is the formal charge of the indicated atom?arrow_forward
