Concept explainers
(a)
Interpretation: All reasonable resonance structures for the given species are to be drawn.
Concept introduction: Resonance structure is a blend of two or more Lewis structures. Resonance structures are represented by a double headed arrow between the structures.

- Nhy is resonance structure A and resonance structure B not the same structure? If you rotate the molecule like a spicket handle (l. e. clockwise with the C at the center and the R group remaining in place as you look down the C - R bond) wouldn't you get the same thing? Why are these not equivalent structures? Resonance structure A t Resonance structure B Actual structurearrow_forwardWhat are resonance structures? What is a resonance hybrid?arrow_forwardLewis structure of SiI4. Any polar bonds in molecule? Polar or non polar?arrow_forward

I. BF3 II. CHBr3 (C is the central atom) III. Cl2 IV. XeBr2 V. PBr5 VI. SCl4 Select the molecule(s) that fit the given statement. Which molecules violate the octet rule?arrow_forward
- 4. a. (i) Describe the octet rule.(ii) Why does the boron trifluoride molecule, BF3, not obey the octet rule? Useformal charges to explain.arrow_forwardConsider the SO 3 molecule. How many valence electrons does the molecule have? How many lone pairs of electrons are on the central atom? How many lone pairs of electrons in total are on the substituent atoms? How many resonance structures can be drawn for the molecule? If the ion doesn't exhibit resonance, indicate "1" as only one structure can be drawn for the molecule.arrow_forwardWhat is meant by a chemical bond? Why do atoms form bonds with each other? Why do some elements exist as molecules in nature instead of as free atoms?arrow_forward
- The “Chemistry in Focus" segment Hiding Carbon Dioxide- discusses attempts at sequestering (storing) underground CO2produced at power plants so as to diminish the: greenhouse effect. Draw all resonance structures of the CO2molecule.arrow_forwardWrite Lewis structures for the following: (a) O2 (b) H2CO (c) AsF3 (d) ClNO (e) SiCl4 (f) H3O+ (g) NH4+ (h) BF4 (i) HCCH (j) ClCN (k) C22+arrow_forwardAn important observation supporting the concept of resonance in the localized electron model was that there are only three different structures of dichlorobenzene (C6H4C10). How does this fact support the concept of resonance (see Exercise 89)?arrow_forward
