Reaction of alkyne with hgso4 and h2so4
WebCorrect option is A) The oxymercuration reaction is an electrophilic addition organic reaction that transforms an alkene into a neutral alcohol. It is electrophilic addition of water to double or triple bond, in presence of mercury sulphate … WebHere's the hydroboration-oxidation of alkyne reaction. So we start with our alkyne. And, once again, usually it's a terminal alkyne. So here's your hydrogen here. And on the other side of our triple bond, let's say there's some R group attached to this carbon. So two are alkyne.
