whakaahuatanga hua
Ko te Neopentane, e kiia ana ko 2,2-dimethylpropane, he awaawa mekameka-rua me nga ngota waro e rima. Ko te neopentane he hau muramura i te pāmahana rūma me te pehanga ka taea te whakakoi ki roto i te wai tino rewa i te ra makariri, i roto i te kaukau tio, i te wa e kopeke ana ki te pehanga teitei ake.
Ko te Neopentane te waro ngawari me te waro hauwhā, he hangarite tetrahedral achiral. Koia tetahi o nga momo hauhanga e toru me te tauira ngota C5H12 (pentanes), ko etahi atu e rua ko te n-pentane me te isopentane. I roto i enei e toru, ko ia anake te hau i nga tikanga paerewa; he wai etahi atu.
