sharaxaada alaabta
Neopentane, oo sidoo kale loo yaqaan 2,2-dimethylpropane, waa silsilad laba-labo ah oo alkane ah oo leh shan atamka kaarboon. Neopentane waa gaas guban kara heerkulka qolka iyo cadaadiska kaas oo isku ururin kara dareere aad u kacsan maalin qabow, qubeyska barafka, ama marka lagu cadaadiyo cadaadis sare.
Neopentane waa alkane ugu fudud oo leh kaarboon afar-geesood ah, wuxuuna leeyahay summeeyaha tetrahedral achiral. Waa mid ka mid ah saddexda isomers qaab-dhismeed oo leh qaaciidada molecular C5H12 (pentane), labada kale waa n-pentane iyo isopentane. Saddexdaas ka mid ah, waa kan keliya ee gaasta ku jira xaaladaha caadiga ah; kuwa kale waa dareere.
