There are two stereoisomers of 1,2-dibromopropene.

Explanation:

The formula of 1,2-dibromopropene is #"CH"_3"CBr=CHBr"#.

Each alkene carbon has two different groups, so the molecule can exhibit #E//Z# isomerism.

The #"Br"# atoms can be on the same side or on opposite sides of the double bond.

Stereoisomers

The first structure is (#E#)-1,2-dibromopropene, and the second structure is (#Z#)-1,2-dibromopropene.
