[24.3] stereoisomerism in complex ions Flashcards
1
Q
what 2 types of stereoisomerism can complex ions display?
A
- cis-trans isomerism
- optical isomerism
2
Q
what molecules show cis-trans isomerism only?
A
four-coordinate and six-coordinate complex ions containing two different monodentate ligands
3
Q
what molecules can show both cis-trans and optical isomerism?
A
six-coordiante complex ions containing monodentate and bidentate ligands
4
Q
square planar complexes: cis-isomer
A
- two identical groups are adjacent to each other
- coordinate bonds between identical ligands are 90° apart
5
Q
square planar complexes: trans-isomer
A
- two identical groups are opposite each other
- coordinate bonds between identical ligands are 180°
6
Q
what is cis-platin?
A
- [Pt(NH₃)₂Cl₂]
- anti-cancer drug
- binds to DNA, preventing cell division
