Alkenes Flashcards
1
Q
Why do alkenes have low boiling and melting point?
A
The pi bonds are weak and have low enthalpy so don’t need much energy to overcome
2
Q
Where is the high electron density in an alkene?
A
The double bond
3
Q
What is the process called when an alkene reacts?
A
Electrophilic addition reaction
4
Q
When a hydrogen-halide molecule breaks bond, which is the elctrophile?
A
The hydrogen atom
5
Q
If an alkene is present what can be used to show its presence?
A
Bromine water
6
Q
What will happen when the solution is reacted with alkene?
A
The solutions goes from orange to colorless when alkene is present
