Seperti yang kita lihat bahwa ikatan rangkap dalam senyawa tersebut mengikat dua gugus yang berbeda yakni CH3 dan H dalam kedua sisinya. As it is a constitutional isomer of butane, it was given the name isobutane. Lets us discuss these isomers below. Polibutena kemudian umum digunakan sebagai kopolimer (bahan campuran polimer lain, selama maupun setelah reaksi), seperti pada bahan perekat yang meleleh pada suhu tinggi. Consider butane: There are also endless other possible ways that this molecule could twist itself. Butane isomers include butane and 2-methylpropane (isobutane) Pentane is made up of three isomers: pentane, 2-methylbutane (isopentane), and 2,2-dimethylpropane (neopentane). These are the isomers which differ in skeletons of carbon atoms. Nama butana berasal dari akar but- (dari asam butirat, dinamai dari kata Yunani untuk mentega) dan ISOMER ALKENA.
