Multiple Choice
Oxalate anions, C2O42−, added to a solution of [Fe(H2O) 6]3+ displace water molecules within the complex ion to form [Fe(C2O4) 3]3−, as shown in the reaction below:[Fe(H2O) 6]3+(aq) + 3 C2O42−(aq) → [Fe(C2O4) 3]3−(aq) + 6 H2O(l) Which of the following does NOT explain why C2O42− displaces H2O in the formation of [Fe(C2O4) 3]3− ?
A) C2O42− has fewer available lone pairs of electrons per oxygen atom than H2O.
B) C2O42− is a stronger Lewis base than H2O.
C) C2O42− forms coordinate bonds more readily than does H2O.
D) C2O42− is negatively charged whereas H2O is uncharged.
