Question

Which layer would p-toluic acid be more soluble if p-toluic acid were added to a two layer mixture of text butyl methyl ether and water?

Answer 1

For us to know in which layer the p-toluic acid will be more soluble, let us lay-out the polarities of each compound:

p-toluic acid = non-polar

tert-butyl methyl ether = non-polar

water = polar

We know that like dissolves like, therefore p-toluic acid will be more soluble in ether.
