Isomerism

Question 1

Structural

Answer 1

Same empirical formula and connectivities but different structural formula

Question 2

Stereoisomerism

Answer 2

Same structural framework but different spatial arrangement of ligands in complex

Question 3

Ionisation isomerism

Answer 3

Results from interchange of anionic ligand within first co-ordination sphere with anion outside co-ordination sphere

Question 4

Hydration isomerism

Answer 4

Interchange of water and another ligand between first and second co-ordination sphere

Question 5

Co-ordination isomerism

Answer 5

Interchange of ligands between 2 metal centres, only possible for salts which cations and anions are complex ions

Question 6

Linkage

Answer 6

One/more ligands can co-ordinate to metal ion in more than one way

Answer 8

Fac and mer

Question 9

Enantiomers

Answer 9

Non-super imposable mirror images
