Alkenes Flashcards
1
Q
What bonds occur in Alkene shapes, and how do they form?
A
Sigma (head on over laps) pi bond (when two p-orbitals side on overlap)
2
Q
How do you draw pi-bonds?
A
For p-orbitals draw figure of eights over the carbons
For pi-bonds draw ovals above and below the carbons
draw a dot in each
3
Q
What is the electrophile?
A
electron pair acceptor
4
Q
What is the nucleophile?
A
electron pair donor
5
Q
How does addition reactions work with cycloalkenes?
A
The double bond breaks and something (halogen?) goes on each end of the double bond
6
Q
How many curly arrows go on addition reactions of alkenes?
A
3
7
Q
What is the name of the reaction of alkenes where the bond breaks?
A
Electrophilic addition
8
Q
What is Markovnikoff addition?
A
Alkene electrophilic additions where two different products can be made
9
Q
What conditions are needed for alkenes to reacted H2 and H2O?
A
H2 = Ni catalyst, 150^oC H2O = H3PO4 catalyst
