Post-Lab Questions react 1. Draw reaction mechanisms used to for the acid base Nitroaniline. Indicate e on each side of the the reactions if the organie compound would be in the sqeuous or organic layer chemist made some significant modifications; the solvent was changed to dichloromethane (d-1.33g/ml) and th order of collecting HA and 8 is reversed (compared to today's lab). With these changes in mind, prepare/draw a flow chart going from left to right. Indicate which layer is which (organic or aqeuous), fill in reagents (NaOH or HCl) and draw structures in thei proper forms, do not use letter designations here. , 4 chemist designed an acid-base extraction separating the same compounds from today's lab.
