Alkenes Flashcards
1
Q
stereoisomers definition
A
- same structural formula
- different arrangement of atoms in space
2
Q
When do E/Z isomers exist in alkenes?
A
- when carbon atoms in the C=C double bond
- are bonded to two different group
- no rotation around the C=C double bond.
3
Q
justify why this structure does not show
stereoisomerism
A
no chiral centre
4
Q
explain why this is the minor product
A
- major product formed from more stable carbocation (tertiary)
- due to positive inductive effect
