Unit 1 - Chirality Flashcards
1
Q
Why are amines not chiral
A
Lone pairs can invert
2
Q
Why are phosphines and sulfoxides chrial
A
Lone pairs are slower to invert due to bulky molecule
3
Q
What are the kinds of chirality
A
Normal, axial and planar
4
Q
Do diastereoisomers have different chemical and physical properties? Why?
A
Yes, they are non-superimposible but not mirror images
5
Q
What kind of molecules form mesoisomers
A
Symmetrical molecules with two chiral centres
6
Q
Why are mesoisomers not enantiomers
A
Rotation about the bond
