Question

There are 3 different possible isomers of a dibromoethene molecule. what are these isomers?

Answer 1

1,1-, (Z)-1,2-, and (E)-1,2-dibromoethene

Step-by-step explanation:

Their structures are shown below.

The 1,2-dibromoethenes (2 and 3) are positional isomers

of 1,1-dibromoethene (1).

(Z)-1,2-dibromoethene (2) and (E)-1,2-dibromoethene (3) are stereoisomers (geometric isomers) of each other.
