Week 11 and 12: pi bonds Flashcards
1
Q
pi bond
A
side-by-side orbital overlap
2
Q
sigma bond
A
end to end orbital overlap
3
Q
Why are alkenes good nucleophiles
A
they are electron rich, meaning they are good electron donors
4
Q
What contributes to the varying stability of alkenes
A
it will depend on how substituted they are because there is more electronic/stabilizing effect. An increase in R groups will increase its capability to engage in productive hyperconjugation
5
Q
Hyperconjugation
A
refers to the interaction of the sp2 and sp3 carbons
6
Q
what scenario would allow both enantiomers of halohydride/hydroboration reactions to be produced?
A
if the alkene can be attacked from both faces (top and bottom)
7
Q
A
