Concept explainers
(a)
Interpretation: An acceptable Lewis structure from the given condensed structure is to be drawn such that all the atoms have a zero formal charge.
Concept introduction: The arrangement of valence electrons among the atoms present in a molecule is represented by the Lewis structure of that molecule. The electron pairs in the molecule are considered to be delocalized.
(b)
Interpretation: An acceptable Lewis structure from the given condensed structure is to be drawn such that all the atoms have a zero formal charge.

- 5. Redraw the following structures below in Lewis form, filling in all of the implied carbon atoms and hydrogen atoms. 6. The following are the reagent, intermediate, and product in a reaction you will learn later in Organic Chemistry. a. Identify any formal charges that are missing from the structures. b. Draw in all lone pairs. c. Redraw the structures with all hydrogen atoms. to t OH ₂arrow_forwardDraw a skeletal structure for the molecules in parts (a) and (b), and a condensed structure for the molecules in parts (c) and (d). a. CH3O(CH2)2COCH = C(CH3)2arrow_forwarda.Give all the structural isomers of the compound C3H5Cl which contains one C=C bond. (Hint: 3 isomers) b.One of the structural isomers in above question shows cis-trans isomerism. Draw and name this pair of isomers.arrow_forward
- is this correct?arrow_forwardConsider the resonance structures of formate. Y-Y > H. Select the true statements about the resonance structures. Each carbon-oxygen bond is somewhere between a single and double bond. Each oxygen atom has a double bond 50% of the time. The actual structure of formate is an average of the two resonance forms. The actual structure of formate switches back and forth between the two resonance forms.arrow_forward4. Multiple structures with the same chemical formula (number and type of each element present) but differing in the atom connectivity are called structural isomers. Use the skeletal structure below to draw a structural isomer of what you have already drawn in Table 4. H O H 0 CN H a. Label the central atoms like you did in Table 4 and name the geometries of each of them.arrow_forward
- 1.44 Draw one valid Lewis structure for each compound. Assume the atoms are arranged as drawn. H HCC NO H a. CH₂N₂ HCNN H H b. CH₂NO₂ HCNO HO C. CH3CNO d. (CH₂CN) HC CN H 1.45 Draw an acceptable Lewis structure from each condensed structure, such that all atoms have zero formal charge. a. diethyl ether, (CH3CH₂)2O, the first general anesthetic used in medical procedures b. acrylonitrile, CH₂CHCN, starting material used to manufacture synthetic Orlon fibers c. dihydroxyacetone, (HOCH₂)₂CO, an ingredient in sunless tanning products d. acetic anhydride, (CH3CO)2O, a reagent used to synthesize aspirinarrow_forwardDetermine if the structural formula below are acceptable Lewis structures for organic compounds. Point out the problems in cases where structure is invalid. CH3 CH;-N-CH-CH3 ČH3 A. This structure is correct because the valance of Nitrogen is complete. B. This is not a correct Lewis structure because Nitrogen can accommodate more atoms. C. This is not a correct Lewis structure because Nitrogen has a charge if it does not have three bonds. D. This is a correct Lewis structure.arrow_forwardFormaldehyde, CH2O, is used as an embalming agent. Draw the structure of CH2O, including lone pairs.arrow_forward
