Phenolyikhompawundi equlethe iringi yebenzene kunye neqela le-hydroxyl.Kwimichiza, i-alcohols ichazwa njengeekhompawundi eziqulethe iqela le-hydroxyl kunye nekhonkco le-hydrocarbon.Ngoko ke, ngokusekelwe kule nkcazo, i-phenol ayilona utywala.

Nangona kunjalo, ukuba sijonga isakhiwo se-phenol, sinokubona ukuba iqulethe iqela le-hydroxyl.Oku kuthetha ukuba i-phenol ineempawu ezithile zotywala.Nangona kunjalo, ukwakheka kwephenol kwahlukile kwisakhiwo sezinye utywala kuba sineringi yebenzene.Le ring ye-benzene inika i-phenol iimpawu zayo ezizodwa kunye neempawu ezahlukileyo kwezo zotywala.

Ngoko, ngokusekelwe kwiimpawu zesakhiwo se-phenol kunye ne-alcohol, sinokuthi i-phenol ayilona utywala.Nangona kunjalo, ukuba sijonga kuphela into yokuba i-phenol iqulethe iqela le-hydroxyl, ngoko ke ineempawu ezithile zotywala.Ngoko ke, impendulo yombuzo othi "Ngaba phenol utywala?"ayinakuba nguewe nje okanye hayi.Kuxhomekeke kumxholo kunye nengcaciso yotywala esibusebenzisayo.
