CHEM 260 Exam 2 Reactions

What happens during a hydrohalogenation reaction?

A hydro halide reacts across an alkene to form an alkyl halide

What happens during a acid catalyzed hydration reaction?

an acid and water react across an alkene to form an alcohol

What happens during a halogenation reaction?

a halogen reacts across an alkene to form two alkyl halides

What happens during a halohydrin formation reaction?

a halogen and water reacts across an alkene to produce an alcohol and an alkyl halide

What happens during an oxymercuration demercuration reaction?

Hg(OAC)2 and H2O react across an alkene to produce an alcohol. NaBH4 reacts with Hg(OAC)2

What happens during a hydroboration oxidation reaction?

BH3 reacts across an alkene, then H2O2 and NaOH react to produce an alcohol.
