6. We can also use the 18 electron guideline to predict the bond order (number of bonds) between two metals in a dimer. For this one forget everything you know about what kind of bonding is possible between two atoms (yes, this is a real molecule).

Consider the molecule shown below. ch_2ohchohchohch_3, Indicate chiral centers and predict the total number of stereoisomers. Draw them out in the Fischer projection. Build a model of one of them (orient it in the Fischer projection) so you can visualize the shape and how the chain curves. Sketch it to the best of your ability. Which of the molecules are enantiomers of each other? Are there any meso compounds? Justify your answers and draw them out. Take a pair of...
