Stereoisomerism Flashcards
1
Q
What is a stereoisomer?
A
Isomers with the same MF same SF different spacial arrangement of atoms
2
Q
What is E-Z isomerism?
A
C=C with two different groups attached to each carbon
3
Q
What is optical isomerism?
A
Contains a chiral centre with 4 different groups attached
4
Q
What are enantiomers?
A
Mirror images that aren’t super imposable
5
Q
How can enantiomers be identified?
A
They rotate the plane of plane polarised light by the same amount but in opposite directions
6
Q
What is a racemic mixture/ racemate?
A
An equimolar mix of 2 enantiomers
7
Q
How many enantiomers usually occur in nature?
A
Usually one hence why the other enantiomer can have harmful side effects e.g thalidomide where the body naturally racemises the mixture
