Draw a structural formula for the following compound: (R)-2-chlorobutane. . Use the wedge/hash bond tools to indicate stereochemistry where it exists. • Use "flat" representations of rings, not chairs, in your drawing. In cases where there is more than one answer, just draw one.

Using a planar pentagon representation for the cyclopentane ring, draw structural formula for trans-1,2-dimethylcyclopentane. • Use the wedge/hash bond tools to indicate stereochemistry where it exists. • Include H atoms at chiral centers only. • In cases where there is more than one answer, just draw one. • Do not include lone pairs in your answer. They will not be considered in the grading. opy aste C. O O O- [* ChemDoodle I...

Draw the structures of the 3 isomers of C8H18 that contain 3 methyl branches on the main chain, 2 of which are on the same carbon.

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 cis-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 where it exists. • In cases where there is more than one answer, just draw one.
