Examine the ungraded ball-and-stick model to determine the three-dimensional structure of the molecule. On the corresponding 2D structure, draw one wedge bond and one dash bond over two existing bonds to indicate the same arrangement of atoms in space. The narrow part of each wedge-and-dash bond should be towards the same central carbon atom. Click on the three-dimensional molecular structure of (S)-1-chloro-2,3-dimethylbutane and drag to rotate it, or use the controls provided. C OH Cl Change two bonds to stereobonds.
