An ether solution of phco2h (a), phnh2 (b), and phch3 (c) is extracted with aqueous naoh. the ether layer will contain what compound(s) after the extraction?

The ether layer will contain aniline and toluene after the extraction.

Explanation:

A solvent extraction is a method to separate compounds or metal complexes, based on their relative solubilities in two different immiscible liquids, usually water and an organic solvent (Ether, in this case).

PhCO₂H (Benzoic acid) reacts with NaOH to form benzoate ion that is very soluble in water but poorly soluble in ether. That means PhCO₂H will be in the aqueous layer.

PhNH₂ (Aniline) is very soluble in organic solvents as ether but poorly soluble in water,

PhCH₃ (Toluene) is soluble in ether but insoluble in water.

That means the ether layer will contain aniline and toluene after the extraction.

I hope it helps!

the correct answer would be d. hope this !

the dissolution of polymer can be thermodynamically described in 2 steps.
