Why is the first step in an electrophilic aromatic bromination reaction so much more endothermic than the first step in an electrophilic addition to an alkene
Calculate ?Sºf for oxalic acid and ?Sº for the combustion of one mole of oxalic acid. c) Calculate ?Gºf for oxalic acid and ?Gº for the combustion of one mole of oxalic acid.
The first mechanism includes sodium acetate to yield beta-penta-acetate and the first mechanism includes zinc chloride (Lewis acid) to form an oxonium ion to yield the alpha-penta-acetate product. Any help to draw out the mechs would be much appre..
