cov khoom piav qhia
Neopentane, tseem hu ua 2,2-dimethylpropane, yog ob-branched-chain alkane nrog tsib carbon atoms. Neopentane yog cov pa taws kub hnyiab ntawm chav tsev kub thiab siab uas tuaj yeem ua rau cov kua dej tsis haum rau hnub txias, hauv chav dej khov, lossis thaum compressed rau siab dua.
Neopentane yog qhov yooj yim alkane nrog quaternary carbon, thiab muaj achiral tetrahedral symmetry. Nws yog ib qho ntawm peb cov qauv isomers nrog cov qauv molecular C5H12 (pentanes), lwm qhov yog n-pentane thiab isopentane. Tawm ntawm peb qhov no, nws tsuas yog ib qho los ua cov pa roj ntawm tus qauv; lwm tus yog kua.
