In the field of organic chemistry, cis isomers contain functional groups on the … WebTraditionally, double bond stereochemistry was described as either cis (Latin, on this side) or trans (Latin, across), in reference to the relative position of substituents on either side of a double bond. A simple example of cis-trans isomerism is the 1,2-disubstituted ethenes, like the dichloroethene (C 2 H 2 Cl 2) isomers shown below.

WebGenerally the number of isomers increases. You can demonstrate this to yourself by drawing all possible structures for propane (1), butanes (2), pentanes (3), and hexanes (5). One way to think about this is as follows: Each carbon you add can attach to any of the carbons already present in any isomer of the molecule.
