丁烷

一种直链烷烃，具有不同的反式交叉与邻位交叉构象。

化学式
C4H10
官能团
烷烃
摩尔质量
58.12 g/mol
Also known as
n-Butane, Diethyl, Methylethylmethane, Butanen, Butani, Butyl hydride

概览

Rotation about the middle bond changes the relative positions of its two methyl groups. The anti arrangement keeps them farther apart than the gauche arrangement. Both are conformations of butane; 2-methylpropane instead has different carbon connectivity.
