Intshayelelo

I-Heterocyclic compounds equkethe i-athomu ezimbini ze-heteronitrogen kwiindawo ze-1 kunye ne-4. I-isomer kwi-pyrimidine kunye ne-pyridazine. Inyibilika emanzini, etywaleni nakwi-ether. Ine-aromatics ebuthathaka, efana ne-pyridine. Akulula ukufumana i-electrophilic substitution reactions, kodwa kulula ukungena kwi-reactions substitution kunye ne-nucleophiles.
