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 1.wt occur during this process  and also2. 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 heated, to boil away NH3 , shift eqm
then the solution is heated and add to NaOH and distillate , to gv product and pass it to HCl , i want to ask 3.wt occur during process  and 4.why inverted funnel is used this time for the product gone to HCl
