Alkenes

How is a Pi bond formed?
p-orbitals overlap above and below the planes of the carbons
1 of 11
What is the bond angle around each carbon?
120
2 of 11
What are stereoisomers?
compounds with the same structural formula, but different arrangement of the atoms in space
3 of 11
What factors determine E/Z isomerism?
a C=C double bond and different groups attached to the carbon atoms
4 of 11
What determines different priorities of atoms of isomers?
Higher atomic number=higher priority
5 of 11
Which bond in a double bond is weaker?
the Pi bond
6 of 11
What are the conditions for hydrogenation of alkenes?
423K and a Nickel catalyst
7 of 11
What is a primary carbocation?
when the positive charge is on the end of a chain
8 of 11
What is a secondary carbocation?
when the positive charge is on a chain with 2 carbon chains attached
9 of 11
Which product of electrophillic addition is the major product?
the secondary carbocation
10 of 11
Why are tertiary carbocations the most stable?
because the positive charge is more spread over the alkyl groups
