Answer:
The possible isomers of C2H2Br2 are Cis- 1,2-dibromoethene, Trans-1,2-dibromoethene and 1,1- dibromethene
Explanation:
Isomerism is the phenomenon whereby organic molecules have the same molecular formular but different structure formular or spatial arrangement.
- When it has different structure formular, then it is referred to as Structural isomerism
- When it has different spatial arrangement, then it is referred to as Stereoisomerism
Dibromoethene has 2 Stereoisomer (Cis- 1,2-dibromoethene andTrans-1,2-dibromoethene ) and 1 structural isomer (1,1- dibromethene)
