Join Yahoo Answers and get 100 points today. There are three structural isomers of pentane and they are: n-pentane is the first isomer which is a straight chain with a normal structure of pentane. Cis-2-Pentene is used in olefin metathesis. There are a total of six different compounds 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. Each contains one double bond within its molecular structure. We could name it 2-butene, but there are actually two such compounds; the double bond results in cis-trans isomerism (Figure \(\PageIndex{3}\)). The rise in demand for polypropylene has encouraged the growth of the DCCU, which is operated very much like an FCCU. C--C--C--C--C The name ends in ene ( just like ethylene) so there is a double bond in there somewhere. The longest chain containing the double bond has five carbon atoms, so the compound is a pentene (rule 1). 3,4 - dimethyl- 1 - pentene is.
