optical isomerism Flashcards
1
Q
definition of optical isomerism
A
same molecular formula, different spatial arrangement of atoms in space
1
Q
when does optical isomerism occur?
A
asymmetrical carbon known as a chiral centre
2
Q
chiral centre
A
four different groups bonded around it so there is no line of symmetry
3
Q
enantiomers
A
two different isomers that are unique due to their effect on plane polarised light. 90 degrees in opposite directions
4
Q
racemic mixtures
A
pair of enantiomers in a 1:1 ratio
