Question 3

How to calculate the oxidation state of the metal

Answer 3

Total Oxidation state of complex - total oxidation state of ligands

Question 4

Optical Isomerism

Answer 4

Compounds with the same molecular formula but different arrangements of atoms in space which result in non superimposable mirror images

Question 5

What is Cis platin

Answer 5

• Anti Cancer drug
• Square planar complex with ;
  A platinum ion
  2 ammonia ligands
  2 Chloride ion ligands
• Binds to DNA in cancer cells, chloride ions are displaced and the complex binds to nitrogen on the DNA in the cancer cells stopping replication
