Final Notes

Question 1

Isomers

Answer 1

different entities (complexes or compounds) made from the same atoms

Question 2

Structural Isomers

Answer 2

same atoms, different bonds

Question 3

Stereoisomers

Answer 3

same atoms and bonds, different spatial arrangements

Question 4

Coordination isomer (structural)

Answer 4

two compounds that differ in composition of the complex ion

Question 5

Linkage isomer (structural)

Answer 5

two complexes that differ by how a ligand binds to the metal

Question 6

Geometric isomer (stereoisomer)

Answer 6

two complexes that have the same atoms and bonds but different relative positions

Question 7

Optical isomer (stereoisomer)

Answer 7

two complexes that are mirror images of each other2

Question 8

Crystal field theory

Answer 8

describes the electron configuration and energies of coordination complexes

Question 9

Crystal field theory for Octahedral complexes

Answer 9

eg is greater than t2g

Question 10

For octahedrals, if the field splitting is large (strong field ligand)…

Answer 10

follow the Aufbau principle

Question 11

For octahedrals, if the field splitting is small (weak field ligand)…

Answer 11

prioritize unpaired spins

Question 12

Ligand field splitting

Answer 12

the difference in energy between the top orbitals and bottom orbitals

Question 13

Crystal field theory for Tetrahedral complexes

Answer 13

t2g is greater than eg

Question 14

For tetrahedrals, when putting e- into orbitals…

Answer 14

prioritize having unpaired spins (like weak-field for octahedral)

Question 15

Different ligands induce…

Answer 15

different amounts of field splitting
