Ama-isomer awahlanganyeli izakhiwo ezifanayo. Izindlela ezimbili eziyinhloko ze-isomerism yi-isomerism yokwakheka noma i-isomerism yomthethosisekelo kanye ne-stereoisomerism noma i-isomerism yendawo. Umbuzo: Yiziphi izinhlobo eziyinhloko ze-isomerism ezaziwa ngokuthi?  <response>: i-isomerism yokwakheka noma i-isomerism yomthethosisekelo kanye ne-stereoisomerism noma i-isomerism yendawo
