how can we ensure that distillation is finished for b.p. about 120 degre..cel.
do we need to check the b.p. during exp. about the range or other method
and also for another exp , we want to prepare the chloride salt of  methy-1-amine
we place acetamide and bromine,then add NaOH, shake it in cool water , yellow solution is formed
i don't know wt occur during this process and also why do we need to shake in cool water, it decrease the rx rate  :'
in fact i think it produce C3COBr , as i think amide react with OH - ,gv out NH3 ,but i want to ask it should be hjeated, to boil away NH3 , shift eqm ,so i get lost
then the solution is heated and add to NaOH and distillate , to gv product and pass it to HCl , i want to ask wt occur during process and why inveryed funnel is used this time for the product go to HCl
