1. Using Hard-Soft Acid Base Theory, predict whether the carbonyl ligands in [Fe(CO)5] bond to the Fe atom via the carbon or oxygen atom. Explain. (2 marks) 2. The pKa1 of \"carbonic acid\" (H2CO3) is reported to be 6.4, which is lower than that predicted by Pauling's rules (pKa1 = 3). Suggest a reason for the unexpected low acidity of carbonic acid.
