Reaction of alkyne with hgso4 and h2so4
WebWhat is the reaction of HgSO 4, H 2 SO 4 with alkynes? Alkenes hydration is done by HgSO 4, H 2 SO 4 and H 2 O. HgSO 4, H 2 SO 4 are behaved as catalysts. HgSO 4 is used because hydrolysis of alkyne is difficult than hydrolysis of alkenes. alkyne to ketone Except ethanal, all other alkynes are conveeted to ketones in hydrolysis of alkynes. 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 …
