Coordination chemistry: reactions and mechanisms
Which of the two complexes W(CO)6 or IrCl(PPh2)2(CO) should undergo the most labile exchange with 13CO. Explain.
The Pt-Rh catalyst in catalytic converters is dispersed on a ceramic substrate rather than as a thin foil. Why is this the case?
Nearly every compound of silicon has this element in the +4 oxidation state. In contrast, most compounds of lead have this element in the +2 oxidation state. a) What general trend of the oxidation states does this observation illustrate? b) What could you suggest as an explanation for this observation?
