BSC 2010C Lecture Notes - Lecture 1: Structural Isomer, Cyclohexene, Chemical Formula
Document Summary
Geometric isomers are a type of structural isomerism where molecules have the same molecular formula but differ in the spatial arrangement of atoms. Geometric isomers occur due to the presence of double bonds or rings in the molecule, which prevent free rotation around the bond axis. The two different arrangements of atoms result in different chemical and physical properties of the molecule. In organic chemistry, geometric isomers are classified as cis or trans isomers based on the orientation of the groups around the double bond. In cis isomers, the substituent groups are located on the same side of the double bond, while in trans isomers, the substituent groups are located on opposite sides of the double bond. One example of a molecule with cis and trans isomers is 2-butene.
