Flashcards in Stereoisomers Deck (4)
What are stereoisomers?
- Stereo isomers are compounds with the same structural formula but with a different arrangement in space.
- Some alkenes have stereoisomers because there is a lack of rotation around C=C.
- There are E-isomers and Z-isomers.
- This is when the double bonded carbon atoms each have 2 different atoms/groups attached to them and when there is restricted rotation.
- Each of the groups linked to C=C is given priority.
- E-isomers when the priority groups are opposite(E).
- Z-isomers when priority groups are on the (Z)ame.
- Special case of E/Z isomerism where the 2 carbons in the double bond have at least 1 group in common and the other attached is H.
- Cis-isomer has the 2 identical groups on same side.
- Trans-isomer has the 2 identical groups on opposite sides.
