10. NAME Consider the octahedral complexes CoX6³ and CoY6³, where the ligands are both monovalent anions (X and Y ). Answer each of the following A. The CoX6³- complex absorbs light at 350 nm, and the CoY6³ complex absorbs light at 400 nm. Which is the stronger field ligand? Y is stronger Both are equal Cannot be determined X is stronger from this information B. CoX6³ is observed to be paramagnetic. Fill in its electron structure on the lines below and indicate whether you believe the X a strong field ligand or a weak field ligand based on this observation. You will receive no credit nless you fill in the arrows indicating the electronic structure in the space provided Weak field Circle one: 11. Strong field Based on the data in the table to the right, present a balanced reaction for the oxidation of C+(aq) to C³+ (aq) by A+ (aq). Also, give the EMF for the reaction. Reduction half-reaction E°(V) A(aq) + e→ A(s) 1.12 B²+(aq) + 2e → B(s) 0.87 C3+(aq) + 2e→C+(aq) -0.12 6
