几何异构几何异构geometricalisomerism在有双键或环状结构的分子中,由于分子中与双键或环相连接的原子或基团的自由旋转受阻碍,存在不同的空间排列而产生的立体异构现象,又称顺反异构。类型①在双键两侧的两个不饱和碳上,分别连有两个不同的原子或基团时,会产生几何异构。例如:随着分子内所含双键数目的增加,几何异构体的数目也随着增加。②联烯或其类似物中取代基均在同一平面上时,也可用顺式、反式,例如:③在含碳-氮双键结构的化合物中,如果与氮原子相连的另一个原子与C=N双键不在一条直线上,而偏在双键的一边,当双键碳原子连有不同的原子或基团时,便存在几何异构体。例如苯甲醛肟有下列两种异构体:通常将羟基和氢位于同侧的称为顺式或同式,在异侧的称为反式或逆式。④含氮-氮双键桸=N椊峁沟幕衔,也有几何异构现象。它们的异构体可以用顺式、反式或同式、逆式区别。例如偶氮苯:⑤环状化合物环上所连原子或基团,由于环的限制不能自由旋转。如果环上有两个或两个以上的碳原子各连有两个不同的原子或基团时,便产生几何异构体。例如,1,4二羧酸环己烷有两种几何异构体:图片⑥环与环并联于1,2位时,也产生顺反异构体,如十氢化萘:
