For Reduction of Vanillin aldehyde to Vanillyl alcohol using Nabh4, Aqueous NaOH and HCl If you incorrectly add acid and do not attain a pH of 1, your yield may be lower than it should be as some of your product would not be isolated. Why won’t it be isolated? Notes: This addition of HCl causes four reactions to occur: a. it hydrolyzes the O-B bond in the intermediate and protonates the oxygen atom that was originally the oxygen atom...
