Geometrical Isomerism -I
Isomers, which have same strucural formula (identical connectivity of atoms ) but different geometry due to different orientation of atom or group of atoms along a bond with restricted rotation (e.g. a double bond or across a ring system).
Geometric isomers are a subtype of configurational isomers that differ in the spatial position around a bond with restricted rotation (e.g. a double bond or across a ring system):
Example 1 :
Geo Isomer 1 : cis & trans 2-Butene
Example 2 :
Geo Isomer 2 : cis & trans -1,2-Dichlorocyclopropane and
Example 3 :
Geo Isomer 3 : Z & E 1-Chloro-1-fluoropropene.
Example 4 :
Geo Isomer 4 : syn & anti Acetaldoxime
Example 5 :
Geo isomer 5 : cis & trans Stilbene
Example 6 :
Geo isomer 6 : cis & trans-1,3-Dichlorocyclobutane
Example 6 :
Geo isomer 7 : cis & transbutenedioicacid [ Maleic & Fumaric Acid ]
