Optical Isomerism A2 Flashcards
1
Q
Define stereoisomerism
A
Same molecular formula but different spacial arrangement
2
Q
Define optical isomerism
A
Two compounds of the same bonds and molecules, but are non-imposable
3
Q
What are enantiomers
A
Two optical isomers
4
Q
What do enantiomers contain
A
A chiral carbon atom, which has 4 different groups bonded to it
5
Q
What is a racemic mixture
A
A mixture of equal amounts of enantiomers
6
Q
How are chirals marked on a diagram
A
With a star above the carbon
7
Q
What is special about enantiomers and optical activity
A
Each enantiomer rotates light in different directions and racemic mixture of a pair of enantiomers will have no effect on light as it rotates both ways the same amount
8
Q
What is a polarimeter
A
Optical rotation is measured using this
