Stereoisomerism Flashcards
1
Q
What is positional isomerism
A
the functional group occupies a different place on the molecule
2
Q
What is optical isomerism
A
Groups occupy a different location around a chiral centre
3
Q
What is a chiral centre
A
A central atom that has four different chains
4
Q
What is geometrical isomerism
A
E-Z isomerism on a double bond caused by the non-rotational bond
5
Q
What is functional isomerism
A
The arrangement changes the functional group eg, aldehydes and ketones
6
Q
What is structural isomerism
A
Branching at different locations
7
Q
How do you identify the different optical isomers
A
Using polarimetry
8
Q
What is a racemic mixture
A
And equal mixture of optical isomers which does not cause the planar light to bend in anyway
