Draw all the isomers of C5H0. 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. The molecular formula fits the formula CHn, which indicates one degree of unsaturation, meaning either a double bond or ring is present. Step 1: Start by drawing all the isomers with double bonds. The simplest case will be a 5-carbon chain where there is a double bond in the main chain. Draw the constitutional isomers that fit this condition. Select / |||||| Draw C H Rings More Erase
