Question

CHE CHE CH3 HC CH3 Br CH3 Br Brs H CH3 2,3-dibromobutane The wedge-dash representation of 2,3-dibromobutane is shown. What is the orientation of the chiral center(s)? 25 Write the orientation as in the following examples, (25) or (2,3S), not 2s or 2,35. Je sure to include the parentheses and the number, and comma as necessar Which of the Newman structures is equivalent to the wedge-dash structure? - D Note that the equivalent Newman structure will not necessarily have the same conformation as the wedge-dash structure.
