The problem: Write an equation to show how you could recover the parent compounds from their respective salts shown in Figure 12.10.
Figure 12.10 is a type of flow chart but I will put it down as best I can. This is an extraction.
R-Phenol + RCOOH + RNH2 + R-(C=O)-R put in ether and aqueous NaHCO3 separates RCOO-Na+ from the rest which are in the ether layer.
Then NaOH added to R-Phenol + RNH2 + R-(C=O)-R yields R=PhenolO-Na+ into the water layer and the other two into the ether layer.
HCl added to RNH2 + R-(C=O)-R and RNH2 separates them into the water and ether layers, respectively.
How does one go about recovering the parent compounds? Does this mean changing the components back into the original compound? Do I just reverse the equations?
Thanks for your input.

Recovering the parent compounds is exactly what you think and yes, you simply reverse the procedure. For example, to recover the parent acid (RCOOH) you neutralize the excess carbonate layer containing the RCOONa (this is an ionic salt of RCOO^- and Na^+) with HCl. The RCOOH ppts. The RNH2 will be present as RNH3^+ + H^+ (again, a salt). The ketone is the only one that survives all of that separation procedure as the original material.ETC.
So I could also add HCl to R-Phenol-Na+ to get R-Phenol-OH and add NaOH to the R-NH3+Cl- to get RNH2?
Thanks from Sheryl
That should happen.
Thanks and have a nice week.
