In organic chemistry lab we just completled a \"LidocaineSynthesis\". I have some questions to clarify before we take the inclass exam.
1. Based on apperence and melting point; how can we validate ifthe crystals are pure lidocaine?
2. When using the seperatory funnel in extraction, we washed theorganic layer with water and would shake then drain the aqueouslayer out. After a couple of washes with water, we then use HCL toextract and collect this aqueous layer seperatley. Following theextraction with HCL we then again washed the organic solution withwater. Any of the washes with water were collected then combined atthe end of using seperatory apparatus. Why would we wash the oganiclayer with water again after using HCL? Does it yeild moreproduct?
3. What compund were we dissolving in the aquoues extract?
