Elimination reactions in halogenoalkanes Flashcards
1
Q
What is eliminated from the molecule?
A
Hydrogen halide
2
Q
What is produced from an elimination reaction?
A
Alkene + hydrogen halide
3
Q
What are the conditions required for the OH- ion to act as a base and cause an elimination reaction in halogenoalkanes?
A
K/NaOH is dissolved in ethanol an mixed with the halogenoalkane
The mixture is heated
Product decolourises bromine water as an alkene is formed
4
Q
Describe the apparatus that could be used for this reaction
A
Mineral wool soaked in reaction mixture in one end of a test tube and heat
Ensure that a bung is in the end of the test tube with a wide going into an upside down test tube in a bowl of water
