Edexcel IAL Chemistry AS 10.8 Halogenoalkane reactions
Edexcel IAL Chemistry AS 10.8 Halogenoalkane reactions
Distinguish aqueous from ethanolic conditions, identify whether OH⁻ acts as nucleophile or base and use sealed heating for ammonia where specified.
How this is tested
- Use aqueous hydroxide for alcohol substitution and ethanolic hydroxide for alkene elimination.
- Use alcoholic KCN to form a nitrile and explain extension of the carbon chain by one.
- Use alcoholic ammonia under pressure to form an amine and state the required conditions.
