Coloured Transition Metal Complex’s

Question 1

What are responsible for many of the colours produced by transition metals

Answer 1

Ligands surrounding the metal ions

Question 2

How do ligands cause colours produced

Answer 2

The interactions between the ligands and the d orbitals.
Ligands will split the d orbitals. X colour of light is absorb by an electron that promotes itself to the other set of d orbitals(d to d transitions).
The complementary colour to that absorbed is the one we see.

Question 3

d orbital splitting can only occur when ..

Answer 3

d orbital is partially filled

Question 4

What controls the colours of light produced by metal complex

Answer 4

Type of ligand used and whether it is a strong field ligand or a weak field ligand
