Geometric isomers are chemical compounds that have the same atoms connected in the same order but differ in their spatial arrangement. They come in two forms: cis isomers have bonds on the same side of a double bond, while trans isomers have bonds on opposite sides. The key difference between geometric and structural isomers is that geometric isomers only differ in their three-dimensional structure rather than atomic connectivity.
Geometric Isomers
- 2. Geometric isomers are two or more chemical compounds that have the same type and same number of atoms. 2 subcategories of Geometric Isomers are Cis- and Trans- The main difference between a structural isomer and a geometric isomer is that geometric isomers differ on arrangement in space while structural isomers differ in connectivity between atoms.
- 3. The reason the Cis is in the name is because the bonds are located on the same side. This side is based on the line that runs vertically through the double-bonded carbons.
- 4. The reason for the trans being in the name is due to the fact that the two outer CH3’s are on opposite sides of the line that runs the double bonded carbons.
- 5. Cis Trans Fun fact: These 2 isomers are hard to separate by means of distillation because of the closeness of their boiling points.
- 6. Geometric isomers differ in three dimensional arrangement. The two sub categories of Geometric isomers are Cis- and Trans- Another name for Geometric isomerism is Cis- Trans isomerism. For it to be a Geometric Isomer, there must be no free rotation around a single bond.
