Stereoisomers share the same connectivity and differ only in the way their atoms are arranged in space. Draw the structure of a compound that is a stereoisomer of trans-1,2-dibromocyclobutane.(Note that the question asks for a different stereoisomer of the named compound and not the named compound itself.)Use the wedge/hash bond tools to indicate stereochemistry. Show stereochemistry in a meso compound. In cases where there is more than one answer, just draw one. (use same instructions below) 1b) Draw the structure of a compound that is a stereoisomer of cis-1,2-dimethylcyclopentane.1c) Draw the structure of a compound that is a stereoisomer of cis-1,2-dimethylcyclobutane.
