There are four stereoisomers of 1-bromo-2-chlorocyclobutane.


The structure of 1-bromo-2-chlorocyclobutane is


#"C1"# and #"C2"# are chiral centres, so the maximum number of stereoisomers is #2^2 = 4#.

We use wedges and dashes to represent stereoisomers.

The possible combinations are wedge-wedge, dash-dash, wedge-dash, and dash-wedge.

The corresponding structures are

4 Structures

There are no internal planes of symmetry, so every structure is a different stereoisomer.
