Answer link. You follow a series of steps. > Step 1. Draw the structure of hexane. Step 2. Convert it to a wedge-dash structure at "C-2" and "C-3". Step 3. Identify the groups on "C-2" and "C-3". The main chain of hexane is the horizontal zig-zag line of carbon atoms. "C-1" is on the left.The carbon skeletons are the same if you look at these two, the only difference is that we changed the wedge to a dash. So that's another very convenient way to draw an enantiomer. If your starting with a wedge, change it to a dash. If your starting with a dash, change it to a wedge. Now let's draw the enantiomer of this compound.Step 1. Draw the bond-line structure of 2-bromopentane. Step 2. Convert this to a wedge-dash structure.
