1. Which of the following mechanisms is most plausible for the following reaction?

a reaction

a) loss of phosphine, b) addition of CO, c) insertion of CO, d) addition of excess CO with reductive elimination of acetone.
a) addition of CO, b) loss of phosphine, c) insertion of CO, d) addition of CO with reductive elimination of acetone.
a) addition of CO, b) insertion of CO, c) reductive elimination of acetone, d) addition of CO, e) loss of phosphine.
a) loss of phosphine, b) addition of CO, d) addition of CO, d) reductive elimination of acetone, d) addition of CO.

2. Which of the following is least likely to undergo a reductive elimination reaction?
Cp2Ti(n-Bu)(H) [(CO)2I3Rh(COMe)]-
(P-iPr3)2PtH2 Cp*2Nb(H)(C2H4)

3. If a complex LnM(A)(B)undergoes facile reductive elimination to give AB and LnM, then what can we say about the reverse reaction, oxidative addition of AB to LnM?
LnM must oxidatively add AB with the same ease.
LnM can not undergo oxidative addition of AB.
Whether LnM can undergo oxidative addition depends on both LnM and AB.
The oxidative addition will be slow compared to the reductive elimination reaction.
