2. Spectroscopy of Carbonyl Complexes
Predict order of C-O stretching frequencies:
[V(CO)6], [V(CO)6]-, [V(CO)6]2-
[Fe(CO)5], [Fe(CO)4(PF3)], [Fe(CO)4(PMe3)]

3. pKa Values of Metal Carbonyl Hydrides
Predict which compound in each pair will have the higher pKa value:
[CoH(CO)4], [CoH(CO)3(PF3)]
[Fe(H)2(CO)4], [FeH(CO)4]-
[Fe(H)2(CO)4], [Fe(H)(Cp)(CO)2]
[Fe(H)(Cp)(CO)2], [Os(H)(Cp)(CO)2]
Hint: consider Hard Soft Acid Base Theory

4. Reactivity of Metal Carbonyl Complexes
Predict which CO in each sequence is most reactive toward electrophilic attack:
