Formation of an imine needs to occur under mildly acidic conditions, yet no acid is started at the start of the reaction. How does imine synthesis succeed? O A No acid is needed when solventless conditions are employed O B The proton transfer is intramolecular, so no additional acid is needed o C The proton transfer is intermolecular, so no additional acid is needed O Glacial acetic acid is added in a subsequent step, which protonates the ion that was...
