Neopentane, inonziwo 2,2-dimethylpropane, ialkane ine-matavi maviri-cheni ine maatomu ekabhoni mashanu. Neopentane igasi rinopfuta patembiricha yekamuri uye kumanikidza kunogona kunyura mumvura inoputika pazuva rinotonhora, mubhavhu rechando, kana kumanikidzwa kune yakanyanya kudzvanywa.
Neopentane ndiyo yakapfava alkane ine quaternary carbon, uye ine achiral tetrahedral symmetry. Ndiyo imwe yeatatu ezvimiro isomers ane molecular formula C5H12 (pentanes), mamwe maviri ari n-pentane uye isopentane. Pakati pezvitatu izvi, ndiyo yega inova gasi pazvimiro zvakajairika; zvimwe zvacho zvinwiwa.
