Cistransmuutokset

Cistransmuutokset, also known as cis-trans isomerism, is a type of stereoisomerism that occurs in molecules containing carbon-carbon double bonds. This phenomenon arises due to the restricted rotation around the double bond, which results in two distinct geometric configurations: cis and trans. In the cis configuration, similar groups are positioned on the same side of the double bond, while in the trans configuration, they are positioned on opposite sides. This type of isomerism is crucial in organic chemistry, as it can significantly affect the physical and chemical properties of molecules. For example, cis and trans isomers of but-2-ene have different boiling points and reactivities. Cistransmuutokset is a fundamental concept in understanding the structure and behavior of organic compounds.
