According to my teacher this
is the correct answer. However would someone be able to explain to
me how ii is eclipsed and why it is not gauche.
1. (1 pts) Draw the Newman projection for the following species, looking down the bond indicated. Identify position between (i) ethyl and methoxy group and (ii) two methyl groups as anti, eclipsed or gauche (circle the answer). HIIT Br (i) anti, eclipsed or gauche (ii) anti, eclipsed or gauche bi

5. Construct a model of 1,2-difluoroethane. Draw the Newman projections for the staggered and eclipsed conformations of 1,2-difluoroethane. Are these molecules isomers or conformers? If they are isomers to what specific category do they belong? 6. The structure of cyclohexane (C6H12) is based on a six membered ring of carbon atoms. Construct a model of cyclohexane. Cyclohexane can exist in two conformations; the boat or chair conformation (shown below). What are the C-C-C, C-C-H, and H-C-H bond angles at each...
