Amongst the following, the most stable complex is
A. [Fe(H4O)6]3
B. [Fe(NH3)6]3+
C. [Fe(C2O4)33-
D. [FeCl6]3-
Answer:C
Amongst the following, the most stable complex is
A. [Fe(H4O)6]3 B. [Fe(NH3)6]3+ C. [Fe(C2O4)33- D. [FeCl6]3-
Explanation: We know that the stability of a complex increases by chelation. Therefore, the most stable complex is [Fe(C2O4)33-.
