Geometric isomerism, also known as cis-trans isomerism, is a form of stereoisomerism that arises due to the restricted rotation around a double bond or in a cyclic compound. It occurs when two different groups are attached to each carbon atom of a double bond or in a cyclic structure, leading to two possible arrangements of these groups in three-dimensional space. Cis and trans isomers have different physical and chemical properties because their spatial arrangements result in different interactions with other molecules or functional groups. This phenomenon is important in organic chemistry, as it impacts the reactivity, stability, and biological activity of compounds, thus influencing their potential applications.
