ʻO Neopentane, i kapa ʻia ʻo 2,2-dimethylpropane, he alkane kaulahao ʻelua me ʻelima mau kalapona kalapona. ʻO ka Neopentane he kinoea lapalapa ma ka lumi wela a me ke kaomi e hiki ke hoʻoheheʻe i loko o kahi wai maʻemaʻe loa i ka lā anuanu, i loko o ka hau hau, a i ʻole ke kaomi ʻana i kahi kaomi kiʻekiʻe.
ʻO Neopentane ka alkane maʻalahi loa me ke kalapona quaternary, a he achiral tetrahedral symmetry. ʻO ia kekahi o nā isomers structural ʻekolu me ka molecular formula C5H12 (pentanes), ʻo nā mea ʻelua ʻelua he n-pentane a me isopentane. Ma waena o kēia mau mea ʻekolu, ʻo ia wale nō ke kinoea ma nā kūlana maʻamau; ʻo nā mea ʻē aʻe he wai.
