Newman projection of 1 2 dichloroethane

WebDraw a Newman projection of the highest energy eclipsed conformation of 1,2-dichloroethane. ANS: ANS : Consider the conformations of 2-methylbutane shown below to answer the following questions. 19. Which of the structures has two gauche interactions? ANS: C ANS : C 20. WebIn 1,2-difluoroethane, shown in two conformations (top) and corresponding Newman projections (bottom), the anti conformation (left) is less stable than the gauche conformation (right). There are two main explanations for the gauche effect: hyperconjugation and bent bonds.
