Alcoholic hydroxyl group (—OH)

(a) At any given chain length, permeability decreases as the number of —OH groups increases

(b) Intramolecular H-bonds formed between adjacent —OH groups result in greater permeability compared with the same compound with nonadjacent —OH groups because of decreased H-bond formation with water
