Unformatted text preview: a) Cl b) 4-isopropylheptane a) 4-chloro-2,5-dimethyl-3-ethylhexane b) 5) Use the partially completed Newman projections formulas below to draw the two staggered conformations of trans-1,2-difluorocyclohexane. One of these is expected to be more polar than the other. Explain. H H C H H C H 2 H 2 C carbon 2 carbon 1 H H C H H C H 2 H 2 C carbon 2 carbon 1 Here are the two requested structures. Of these, the first is expected to be considerably less polar than the second, since the fluorines are anti to each other. H H C H H C H 2 H 2 C carbon 2 carbon 1 H F H F H H C H H F C H 2 H H 2 C F H carbon 2 carbon 1...
