Draw two cyclic constitutional isomers of cis-1-chloro-2-methylcyclobutane with the same size ring. In cases where there is only one cyclic constitutional isomer, just draw one structure.

The drawings are in the figure attached below.

Explanation:

"Constitutional isomers" is a term used in chemistry to refer to chemical compounds that have the same constitution and molecular formula distributed in a different structure. That is, the compound has the same atoms, but when built in a three-dimensional image, these atoms occupy different places within the same structure.
