Geometric isomers ( cis trans )

Cis and trans isomers have the same number of carbons and hydrogens but differ in their spatial arrangements. Cis-2-butene has substituents on the same side, while trans-2-butene has them on opposite sides. Geometric isomers exclude mirror-image arrangements and instead refer only to differences in molecular structure from bond rotations. The key difference between cis and trans isomers is the spatial arrangement of their substituents.

Geometric isomers ( cis trans )
- 1. Geometric Isomers ( cis-trans ) By Mary Goode
- 2. What is the same and what is different about these two geometric isomers? They have the same number of carbons and hydrogen, but they are arranged differently. One is called cis-2-butene and the other is called trans-2-butene, why? “CIS” means on the same side and “TRANS” means across; therefore, they are called this because of the way they are arranged.
- 3. Cis-2-butene ( on the same side )
- 5. Geometric Isomerism is another form of stereoisomerism. Geometric Isomers exclude any different arrangements which are due to the molecule rotating as a whole, OR rotating about particular bonds.
- 6. In conclusion… An isomer is a structure in which you have the same amount of certain molecule, yet they are arranged differently. The most important thing that I learned is the difference between “cis” and “trans”
