Question
n part A of the zynthesis of Lidocains you will have to perform multiple extractionz. Anewer the following cuestions with the carrect match. 40-50 ml ot BM KOH was added to damp salid and the pH at the solution was acjusted to ba above 10. You coolad ??? aqueous sclution and transtemed it to the separatery funnel, addes diethyl ether and have shaken the funnel several times. which layer will be aqueous laver, top or bottem? Potaszlum chicrice and stannic hydrexdde wbe the Inorganl praducts ot the reaction wlth KOH. In which layer theylbe tound atter wo oquantial Chocse.. extractions with diethyl ether, etheral layer ur aqueous layer? 40-50 ml of BM HODH was added to damp solid and the pH cf the "lution was acjusted to b2?bovc 10. You cooled ??? aqucous scludon and transferred it to the yepdratory fu"r 1 dn perfo''ned twv sequential extract uns ith ?'ethyl ether. In which Idyer, dqueous ur etheral the product 2,6 tímetlry dnilmeril be hocsc the separatcry tunnel and tirst portion ct diathyl ethar extracted the aquaaus ayar. Which layar you will place back Into saparatory tunnel to extract it sconc time with diethyl ether, aqueous or etheralExplanation / Answer
1. The bottom layer will be the aqueous layer since water is denser than diethyl ether.
2. Potassium chloride and stannic hydroxide will be found in aqueous layer as they are ionic compounds which are soluble in water.
3. 2,6-dimethylaniline will be found in the etheral layer as the neutral molecules go into organic layers.
4. The aqueous layer will be placed back into the separatory funnel to extract it the second time with the diethyl ether.
