Question 1

Eq for d-electron count?

Answer 1

=group number - oxidation state

Question 2

are ligands lewis acids or bases?

Answer 2

lewis bases (electron pair donors)

Question 3

are metal atoms lewis acids or bases?

Answer 3

lewis acids (electron pair acceptors)

Question 4

what are some bidentate ligands?

Answer 4

acetoacetonate (acac), ethandioate/oxalate (C2O4^2-), ethylenediamine (en)

Question 5

how many e- do bidentate ligands donate in total?

Answer 5

4e-

Question 6

what are the isomers for sq planar always?

Answer 6

cis and trans

Question 7

what are the isomers for a metal with 2 ligand types with 3 of each?

Answer 7

fac and mer

Question 8

what are the isomers for a metal with 2 of one ligand and 4 of another ligand?

Answer 8

cis and trans

Question 9

what is the difference between enantiomers and isomers?

Answer 9

enantiomers = optical with the different shaped bonds

isomers = position of atoms

Question 10

eq for metal oxidation state?

Answer 10

= overall charge on the complex - total formal charge on the ligands

Question 11

what gives a complex higher pKa?

Answer 11

1) more neutral ligands (e.g. CO) to stabilise the negative charge when a proton leaves - the most stable conjugate base gives a stronger acid

2) a more protic/electronegative metal so the proton is removed more readily

3) if the COMPLEX is negatively charged - it will be unfavourable for it to become more negatively charged by removal of a proton, so the eqm will lie towards this species (acidic)

Question 12

what are reduction and oxidation in terms of e-?

Answer 12

reduction = addition of e-
oxidation = removal of e-

Question 13

what mechanism is given by negative entropy (S)?

Answer 13

associative

Question 14

charge of Me ligand?

Answer 14
