Draw all the isomers of C-H10. Clearly show stereochemistry if stereoisomers are possible.
Step 1: Start by drawing all the isomers with double bonds. • Consider constitutional isomers, then stereoisomers. Step 2: Draw all isomers containing a ring. • Consider constitutional isomers, then stereoisomers.
Step 2: Next consider isomers containing a ring. The largest ring possible with this molecular formula contains 5 carbons, while the smallest possible ring contains 3 carbons. Draw an isomer containing a 5-carbon ring. Consider a 4-carbon ring of C-H10. Draw stereoisomers, if applicable.
