Ko te rōpū amide ko acetamide (ethanamide). Ko te reira i te pūnaha extensively conjugated, rite te kotahi takirua mokemoke i runga i te hāora hydroxyl, te kapua pi benzene, te takirua mokemoke hauota, te orbital p i runga i te waro carbonyl, me te kotahi takirua mokemoke i runga i te hāora carbonyl e katoa conjugated. Ko te aroaro o e rua ngā rōpū whakahohe hanga ano te mowhiti benzene tino urupare ki electrophilic whakakapi aromatic. rite te whakakapi he ortho, para-directing me te para ki te whakaaro ki ia atu ki te tahi i te tahi, katoa ngā tūranga i runga i te mowhiti e neke atu ranei iti iho ōrite. te whakahohe whakahohe
