(a) Assuming the 18 electron rule is obeyed, write down the values of x, y and z and the oxidation state of the metal in all of the following: [Ru(Cp)(CO)x], [lr(PR3)2(H2)2(H)y]*, [Mn(CO)z(4-1)]2 [3] (b) Write a balanced equation for the reaction of zirconium tetrachloride with four equivalents of benzyl magnesium chloride. Draw a structural diagram of the organometallic product of this reaction, making sure to show the stereochemistry. [2] (c) One of the two following rhodium compounds is thermally unstable: [Rh(C2H5)(CO)(PPh3)2] and [Rh(C2H5)(CO).]2+ (0) Determine (with full reasoning) which of the two compounds is thermally unstable and name the principle reaction type by which this compound decomposes. [2] (ii) Determine the formula of the rhodium product of thermal decomposition in (c)(1), assuming carbon monoxide to be in excess. Count the valence electrons and determine the oxidation state of rhodium in your product. [3]
