WebThis alkoxide is protonated by the solvent (usually methanol). Explain why this reduction is NOT reversible. In order for it to reverse, which species would have to leave the molecule? Provide another example of an irreversible addition to a ketone. Show the reagent and the product, and explain why this reaction will not reverse. WebSodium borohydride is an odorless white to gray-white microcrystalline powder that often forms lumps. It can be purified by recrystallization from warm (50 °C) diglyme. Sodium borohydride is soluble in protic solvents … WebIf all four hydrogens from NaBH4 are transfused, then a borate salt can made, which will decompose uon to addition of water.
