Neopentane, yomwe imatchedwanso 2,2-dimethylpropane, ndi alkane yokhala ndi nthambi ziwiri yokhala ndi maatomu asanu a kaboni. Neopentane ndi mpweya woyaka kutentha kutentha ndi kupanikizika komwe kungathe kusungunuka m'madzi otentha kwambiri pa tsiku lozizira, mumadzi osambira oundana, kapena kupanikizika kwambiri.
Neopentane ndi alkane yosavuta kwambiri yokhala ndi quaternary carbon, ndipo ili ndi achiral tetrahedral symmetry. Ndi imodzi mwa ma isomers atatu omwe ali ndi mamolekyu a C5H12 (pentanes), ena awiri ndi n-pentane ndi isopentane. Mwa zitatu izi, ndi imodzi yokha kukhala gasi pa muyezo muyezo; zina ndi zamadzimadzi.
