In this experiment 1-butanol is converted to 1-bromobutane by an sn2 reaction in general, a primary alkyl bromide can be prepared by heating the corresponding alcohol with (1) constant-boiling hydrobromic acid (47% hbr), (2) an aqueous solution of sodium bromide and excess sulfuric acid, which is an equilibrium.
- The reactions conditions are controlled using this acid also by using distillation to purify compounds which have repetitively high boiling points these practices are used to control the conditions by taking advantage of the chemical properties which the chemist can.
- The sulphuric acid serves as two purposes which is to increases the amount of protonated alcohols present in the reaction mixture and to help tie up the water molecules generated in the reaction shifting the equilibrium in favor of the alkyl bromide an alternative and more covenient method involves the in situ generation oh hydrobromic acid by .
