Question

benzene is a polar molecular, but not polar solvent. In light of cation- pi interaction and other molecular recognition affects involving benzene that we have discuss above, explain why KCal is solute in water but not in benzene

Answer 1

Assume KCal is actually KCl, Potassium Chloride, which is pretty soluble in water...

This is a anion + cation, K+ and Cl-

therefore, this will form aqueous solution readily, since H2O has dipole so the positive charges attack Cl- ion and negative pole attacks K+

therefore

they will become ionic in solutoin

For benzene, this is organic

So th eonly thing that will happen is a slight ion-dipole induce forces

but they will NOT be soluble since the benzene organic layer will not hdyrolyse the salt
