Pentenes (also called Pentylenes) are alkenes with the chemical formula C 5H 10. Each contains one double bond within its molecular structure. Six different compounds are in this class, differing from each other by whether the carbon atoms are attached linearly or in a branched structure, and whether the double bond has a cis or trans form. WebStilbene exists as two possible stereoisomers.One is trans-1,2-diphenylethylene, called (E)-stilbene or trans-stilbene.The second is cis-1,2-diphenylethylene, called ()-stilbene or cis-stilbene, and is sterically hindered and less stable because the steric interactions force the aromatic rings out-of-plane and prevent conjugation.
