The ability of NH3 to form coordination compounds with transition metal ions can best be accounted for by the fact that NH3:
A. Acts as an electron pair donor
B. is capable of H bonding
C. Is a weak base in aqueous solution
D. Contains N with a -3 oxidation number
answer: A
Im confused about this one.
NH3 does act as an electron donor because its in a covalent bond and the passage basically gives that answer away. But NH3 is ALSO a weak base in solution which again makes it an electron donor and CO3+ its Lewis Acid electron acceptor.
So... With that logic, it looks to me as if 2 answers, A and C are correct. How do you ascertain which is "best"???
