1,2-dimethylcyclopropane
Quick Summary
1,2-dimethylcyclopropane is a chemical compound that exists as stereoisomers. Stereoisomers have the same molecular formula and constitution but differ in the spatial arrangement of their atoms.12
In the case of 1,2-dimethylcyclopropane, the two methyl groups can be positioned on the same side of the cyclopropane ring (cis) or on opposite sides (trans). These different spatial arrangements result in distinct compounds with unique properties, such as different boiling points. The cis isomer is achiral, while the trans isomer exists as a pair of enantiomers.12
