WebWhat goes in the organic layer? There is the organic layer, which is insoluble in water and initially contains all of your compounds that you will eventually separate. The organic layer also contains a solvent (CH2Cl2 or ether) that is insoluble in water. So the organic layer= Compounds we’re trying to separate + insoluble solvent. WebIt is now soluble in water but insoluble in ether. At this point, the deprotonated organic salt would reside in the aqueous layer (Figure 1). in ether NH On naphthalene benzoic acid NaOH HO NH 00 Na in ether aniline in water Figurel.
