I have an assignment and i am stuck on all parts of this question! If someone could answer it, it would be amazing! I have to submit my paper in 8 hours and was going to skip this question!
1. (i) Use group theory to predict the number of (CO) stretching
vibrations you would expect to observe in the IR and Raman
spectra of all sensible isomers of Fe(CO)4(PPh3).
(10 marks)
(ii) Can these isomers be differentiated by IR and/or 13C {
1H}
spectroscopy at room temperature? Fully explain your answer in
both cases.
(10 marks)
(iii) Fe(CO)5 is relatively unstable and upon standing converts into
a green solid. What is the latter? Give a balanced equation.
Would you expect to be able to differentiate between these two
iron carbonyls on the basis of IR spectroscopy? (you do not need
to give a full group theory analysis)
(5 marks)
(iv) Explain why Fe(CO)4(PPh3) does not decompose in a similar
manner but is sensitive to oxidative decay.
(5 marks)

Re: EMERGENCY HELP WITH INORGANIC QUESTION!!!
I dont have knowledge in Raman Spectroskopy.
But iii I think I can answer.
3 Fe(CO)5 => Fe3(CO)12 + 3 CO green
Also 2 Fe(CO)5 => Fe2(CO)9 + CO yellow
iv I think its because of the Triphenylphosphan, what is sensitive to oxygen.
