17.36. For each of the following molecules, list all symmetry operations, assign the point group, and answer any associated questions. F. F a. 1,1-difluorocyclopropane: H2C-CH2 How many peaks are expected in the 13C NMR spectrum of 1,1-difluorocyclopropane? Justify your response in terms of specific symmetry operations (or a lack thereof). F CH b. trans-1,2-difluorocyclopropane: H₂C CH F Is trans-1,2-difluorocyclopropane polar? Briefly (1-2 sentences/concepts) use the presence or lack of specific symmetry elements to justify your response. F. C. This tetrafluorospiro[2.2]pentane: F F Is this molecule chiral? Briefly (1-2 sentences/concepts) use the presence or lack of specific symmetry operations to justify your response. CI e. trans-1,2-dichlorocyclobutane: -CH₂ d. cis-1,2-dichlorocyclobutane: (Assume a planar conformation for 17.36 d through g.)
