Transition Elements 2 - Stereoisomerism

Question	Answer
What are stereoisomers?	molecules with same connectivity but different spatial arrangement
What type of stereoisomerism do complex ions exhibit?	Cis-Trans Optical
What conditions are required for stereoisomerism in square planar structures?	4 co-ordinate bonds 2 different monodentate ligands
How do complex ions bend the rules of cis-trans stereoisomerism?	In organic meant to have C=C Not necessary for complex ions
Arrangement of ligands in square planar structures	Ligands are arranged in the same plane at the corners of a square with 90' bond angles
Arrangements of identical ligands in cis-isomerism of square planars	Two identical groups are adjacent to each other 90' apart
Arrangement of identical ligands in trans- square planar	Identical ligands are opposite each other 180' apart
Optical isomerism only occurs in what? What conditions must be met?	octahedral complexes Must have 2 or more bidentate ligands
How does cis-platin work?	Forms Pt complex in cell Binds to DNA Prevents DNA replication Triggers apoptosis
