Aldehydes and Ketones - Nucleophillic Addition - Chiral products Flashcards
1
Q
How to produce an isomer with HCN
A
Reaction of HCN with aldehydes and assymetrical ketones gives rise to optical isomers
2
Q
Why is the ;CN- can attacking C delta plus from etiher side so significant?
A
The chances of it attacking either side is 50:50
3
Q
Once reacted with HCN , what shape is the carbonyl
A
Trigonal planar
4
Q
If it is attacked from both sides what will it produce?
A
2 different optical isomers in equimolar quantities
5
Q
What is formed in equimolar quantities?
A
Racemic mixture formed
6
Q
What will a racemic mixture affect on plane polarised light?
A
No overall effect
