(E)-Pent-2-ene (trans-2-Pentene) C5H10

Section 2-8. Constitutional isomers of C5H10. III.

Yet a third molecule with the 5 carbons in a 'straight' chain, differing from isomer II at the double bond. Still between carbons 2 and 3, the geometry has the two ends of the molecule across the double bond rather than on the same side. Isomers, such as cis- and trans-pent-2-ene, which differ only in the three-dimensional arrangement of the atoms in space are called stereoisomers. Bp 36°C.
