stereochemistry and configuration Flashcards
1
Q
what is a stereoisomer
A
isomers which only differ in the spacial arrangement of atoms and not the bonds.
2
Q
what are the 2 types of stereoisomers
A
enantiomers and destereoisomers
3
Q
what is a racemic mixture
A
50:50 mixture of both types of enantiomers
4
Q
how do you tell the difference between enantiomers experimentally
A
plane of polarised light (they rotate the light in equal but opposite directions)
5
Q
what is a destereoisomer?
A
a stereoisomer which is not an enantiomer
6
Q
the number of possible stereoisomers for a molecule with n stereo centres is …
A
2^n
