Explain Geometrical Isomerism
The molecular composition of a chemical compound plays an important part in forming the functional as well as imparting physical as well as chemical characteristics to the formed chemical structures. Various factors play an important part in this. The molecular arrangement is one of the most vital factors of chemical compound stability. Hence the narrative would focus on briefly describing Geometrical Isomerism along with an example.
The chemical structure of molecules plays a vital part in defining the fundamental function as well as the molecular interaction of the compound. Isomers are forms or chemical molecules that contain a similar molecule-based formula structure but differ in having a varied arrangement of structural atomic constituents in the physical space. Geometrical Isomerism is a special form of stereoisomerism in which the structural atomic units constituting the isomer are placed in a similar arrangement but they persist to provide a vivid spatial order of the structure in the physical space of the molecule. Especially it is also important to remember in the case of a geometrical isomer that the rotation of molecules is disrupted which leads to the production of different forms of molecular alignments. Geometrical isomerism as already mentioned is a type of stereoisomerism which differs from structural isomer forms in the specific aspect of considering the rotation of the molecule. Generally, the forms of geometrical isomerism mainly occur due to the rotation of the atomic constituents in the molecule as a total aspect or as around rotation based on particular bonds such as double bonds, triple bonds, etc. Geometrical isomerism is primarily observed under compounds of organic chemistry and has two other common names such as:
- Cis-trans isomer form
- E-Z isomer types
