U fiirso qoraalka hoose ka dibna ka jawaab su'aasha kadib isla luqadda qoraalka:  Gelitaanka: Paracetamol wuxuu ka kooban yahay halbeeg benzene ah, oo lagu beddelay hal koox hydroxyl ah iyo atomka nitrogen ee kooxda amide ee qaabka para (1,4). Kooxda amide waa acetamide (ethanamide). Waa nidaam si ballaaran loo iswaafajiyay, sida hal lammaane oo keli ah oo ku saabsan oksijiinta hydroxyl, daruuraha benzene pi, lammaanaha kali ah ee nitrogen, p orbital on carbon carbonyl, iyo hal lammaane oo keli ah oo ku saabsan oksijiinta carbonyl ayaa dhammaantood la iswaafajiyay. Joogitaanka laba kooxood oo firfircoon ayaa sidoo kale ka dhigaya giraanta benzene inay aad ugu falceliso beddelaadda aromatic electrophilic. Maadaama bedelayaashu yihiin ortho, para-directing iyo para midba midka kale, dhammaan jagooyinka ku jira giraanta ayaa si isku mid ah loo hawlgeliyay. Isku xidhka ayaa sidoo kale si weyn u yareeya aasaaska oksijiinta iyo nitrogen-ka, iyadoo hydroxyl-ka laga dhigayo mid aashito leh iyada oo loo marayo kala-goynta lacag ee lagu horumariyay anion-ka phenoxide.  Su'aal: Maxaa dhaca marka la is waafajiyo kadib?
wuxuu yareeyaa aasaaska oksijiinta iyo nitrogen-ka
