What is responsible for the differences in chemical shift observed in carbon 4 in 4-fluoroheptane and carbon 4 in heptane? 2 Check all that apply View Available Hint(s) The electronegative fluorine atom generates a partial positive charge on carbon 4, which results in a downfield shift of the carbon signal. There is no difference in the chemical environment between the carbon 4 in heptane and 4-fluoroheptane, so there is no difference in chemical shift. The hybridization of carbon 4 has...

Why do amide bonds exist as reasonably stable s-cis or s-trans isomers at room temperature? a. These amide bonds are not stable. b. There is partial double bond character between the carbonyl carbon and the nitrogen atom. c. The oxygen atom is hydrogen-bonded with the nitrogen atom. d. The side-chains can form hydrogen bonds. e. None of the above is correct.
