乳酸分子具有几个对映异构体?
有2个对映异构体。
互为实物与镜像而不可重叠的立体异构体,称为对映异构体 (Enantiomer,简称为对映体),对映异构体都有旋光性,其中一个是左旋的,一个是右旋的,所以对映异构体又称为旋光异构体。
1、两个互为镜像而不能重合的立体异构体,称为对映异构体,简称对映体。
2、对映体是指具有相同分子式的化合物中,由于原子在空间配置不同而引起的同分异构现象。
3、互为旋光异构体的两种化合物,由于其中一个不对称碳原子的取代基在空间上取向不同而互成物体与镜像的关系,并且两者在空间上不能重叠,它们被称为对映体。
乳酸分子具有几个对映异构体?
乳酸分子有两种对映异构体。
即同一有机化合物可能有不同的对映异构体。
