Assume that each of these molecule satisfies the 18-electron rule. Calculate the number of metal-metal bonds and sketch the molecule. [Mn2(CO)10] ? -CO-[(?4 -C4H4)Fe(CO)2]2
What are the electron counts for each Rh compound in the

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). LorX e(CS) e (NL) Cr H20 ?-OAc" n/a anion (neutral) Cr-Cr bond TOTAL * Note that there are "two ends" to each acetate (see text of #3). Make sure each Cr gets an equal...
Draw the Lewis structures for Co, and co, and predict the number of and bonds for each molecule. (Assign tone pars and radical electrons where appropriate. Omitaw formal cham (s) CO2 Lewis structure Marvin JS Helo Edit drawing o bonds bonds (b) CO Lewis structure
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...
3. Use the 18-electron concept to calculate the number of metal-metal bonds in the multinuclear complex, [Fes(CO)12. Deduce the geometry of the metal-metal framework.

5. In organometallic complexes, the 18-electron rule is used to predict the number of donor groups attached to the metal ion and its orientation Propose a possible structure for the following compounds: a. i.
