Cis and trans stereoisomers

WebTo make the cis and trans stereoisomers, we can link the methyl groups in one of two methods. Cis-2-butene's structural formula is: H H │ │ H─C─C=C─C─H │ │ CH3 CH3. The two methyl groups are situated on the same side of the double bond, as you can see. Trans-2-butene's structural formula is: H H │ │ http://research.cm.utexas.edu/nbauld/teach/stereo.html
