Faasino i le vaega o loo i lalo ma tali le fesili mulimuli ane i le gagana lava lea e tasi e pei o le vaega:  Faʻamatalaga: I le kemisi, o isomers o ni ion poʻo ni molecules e tutusa a latou metotia ae eseese a latou fausaga. E lē faapea e tutusa uiga o isomeru. E lua ituaiga autu o isomerism o isomerism fausaga (po isomerism faavae) ma stereoisomerism (po isomerism spatial).  Fesili: O ā ituaiga o isomerism e masani ona taʻua?
