I-Phenoliyinhlanganisela equkethe indandatho ye-benzene kanye neqembu le-hydroxyl.Ekhemistry, utshwala buchazwa njengezinhlanganisela eziqukethe iqembu le-hydroxyl kanye neketango le-hydrocarbon.Ngakho-ke, ngokusekelwe kule ncazelo, i-phenol ayilona utshwala.

Kodwa-ke, uma sibheka ukwakheka kwe-phenol, singabona ukuthi iqukethe iqembu le-hydroxyl.Lokhu kusho ukuthi i-phenol inezici ezithile zotshwala.Nokho, ukwakheka kwe-phenol kwehlukile kunesakhiwo sobunye utshwala ngoba iqukethe iringi ye-benzene.Le ring ye-benzene inikeza i-phenol izici zayo ezihlukile nezici ezihlukile kulezo zotshwala.

Ngakho-ke, ngokusekelwe ezicini zesakhiwo se-phenol ne-alcohol, singasho ukuthi i-phenol ayiyona utshwala.Kodwa-ke, uma sibheka kuphela iqiniso lokuthi i-phenol iqukethe iqembu le-hydroxyl, khona-ke inezici ezithile zotshwala.Ngakho-ke, impendulo yombuzo othi "Ingabe i-phenol utshwala?"angeke kube nguyebo noma cha.Kuya ngomongo kanye nencazelo yotshwala esibusebenzisayo.
