Isomerism: Geometric (cis/trans) isomers With a molecule such

Geometric (cis/trans) isomers With a molecule such as 2-butene, a different type of isomerism called geometric isomerism can be observed. Geometric isomers are isomers in which the order of atom bonding is the same but the arrangement of atoms in space is different. The double bond in an alkene is not free to rotate because of the nature of the bond. Therefore, there are two different ways to construct the 2-butene molecule (see figure below). The image below shows the two geometric isomers ... What is an isomer. How do isomers differ from one another. What are their different types. Check out a few examples, along with structures and diagrams. Isomerism Definition Compounds which have same molecular formula but differ in modes of combination or arrangement of atoms within the molecule are known as isomers and this phenomenon is know as isomerism . Isomers can have different physical or chemical properties. As for example, the cis and trans isomers of but-2-ene are as follows: Image source: wikimedia commons by JaGa Classification of isomerism There are two main types of isomerism - structural isomerism and stereoisomerism. These can ...
