1. What is meant by the term transition metal? State at least two general properties
of transition metals.
Incomplete d-orbitals. Found in groups 3 – 12 of Periodic Table
Any two from:




Form coloured compounds
Have varying oxidation states (numbers)
Form complexes with ligands
Have catalytic functions
2. Outline the difference(s) between Unidentate, Bidentate and Multidentate ligands.
From the refcodes below, outline the ligand type for each:
AWEGOZ
BEBDAO
AENIN
AGOJUB
Unidentate – attached by 1 bond
AWEGOZ
Bidentate – attached by 2 bonds
AEININ
Multidentate – attached by many bonds
