#1
Front (Question)
What is optical isomerism?
Back (Answer)
Occurs when organic molecules have a chiral centre. They are isomers with non-superimposable images of each other
#2
Front (Question)
What is an enantiomer?
Back (Answer)
What you call an isomer
#3
Front (Question)
How many isomers are possible for each chiral centre?
Back (Answer)
2. Total number of isomers = 2^ no. chiral centres
#4
Front (Question)
What are the steps to drawing a 3D representation of an optical isomer?
Back (Answer)
• Identify chiral centre • Draw an empty tetrahedral molecule with C at centre • Position atoms • Mirror your drawing
#5
Front (Question)
What are the steps when drawing opitcal isomers with 2 chiral centres?
Back (Answer)
Mirror the entire thing (both centres) Mirror top chiral centre only Mirror bottom chiral centre only
