C13 - Alkenes Flashcards
1
Q
Define stereoisomers
A
Same structural formula but different positions in space
2
Q
What are the conditions for E/Z isomerism
A
A double bonds (to limit rotation)
Different groups on each side of the double bond
3
Q
What bonding is present in alkenes
A
Sigma bonds and pi bonds
4
Q
What is a pie bond
A
Perpendicular overlapping of P orbitals
Forms the cloud above and below plane
5
Q
What are the cahn – in gold – pre-log Rules
A
In EZ isomerism, the group with the highest priority is that with the higher atomic number
6
Q
State my markownikoff’s rule
A
More substituted carbocation Intermediates are more stable, therefore more likel’y to form
