A. Preparation of [Ru(phen)3)][PF6]2 Charge a 100 mL RBF with 50 mL ethylene glycol and stir bar. Weigh out and add 1.8 g phenanthroline (10 mmol) and 0.45 g RuCl3H2O (~1.8 mmol). Equip with heating mantle and reflux condenser and gently reflux for 2 h. Filter hot and transfer to a beaker, add 70 mL water and a stir bar. Separately, dissolve ~1 g of ammonium hexafluorophosphate in 10 mL water and add this to the filtered solution dropwise (with constant stirring) to precipitate the product, filter, wash with water, and place in the oven at 60-80 C to dry until the next class period. Once dry, obtain the product mass. Obtain the 1H-NMR spectra of the product and phenanthroline in do- acetone. Put at least 10 mg in the NMR tube. Calculate the % yield and obtain the 1H-NMR spectrum in de-acetone. Put at least 10 mg in the NMR tube.

Consider the following reaction: [Cr(H2O)5(SCN)]2+ + Yn- --> [Cr(H2O)5Y](3-n)+ + SCN- Which statement is true if this reaction occurs via a dissociation mechanism? Group of answer choices Changing the incoming ligand, Yn-, will have a large effect on the rate constant. The first step of the mechanism is the addition of the Yn- ligand to form a 7-ccordinate intermediate, [Cr(H2O)5(SCN)Y](2-n)+ Changing the incoming ligand, Yn-, will have very little effect on the rate constant. It is impossible for this reaction to occur via a dissociation mechanism.
