The oxymercuration reaction is an electrophilic addition reaction, an alkene undergoes oxymercuration and forms neutral alcohol.
Anti-Markovnikov’s rule: unsymmetrical alkene reacts with hydrogen halide, halide ions (negative part) goes to the less substitution position of carbon-carbon double bond which provides
Markovnikov addition: unsymmetrical alkene reacts with hydrogen halide, halide ions (negative part) goes to the more substitution position of carbon-carbon double bond which provides alkyl halides.
