Chemical test for halogenoalkanes?
Hey, just wondering if someone could tell me what this is as I can't find it explicitly in the book. I think it's do something to release the halide and add silver nitrate solution and identify white/cream/yellow precipitate (depending on halogen present)?
Thanks!
Thanks!
test: heat under reflux with sodium hydroxide solution, then acidify with dilute nitric acid. add silver nitrate solution.
observation: chloride gives a white ppte that is soluble in dilute ammonia
bromides give a cream ppte that is insoluble in dilute ammonia but soluble in concentrated ammonia.
iodides give a yellow ppte that is insoluble in both ammonia.
