propin
Propin is a chemical compound with the molecular formula C3H8. It is the simplest alkane to contain a chiral center. Specifically, it is propane where one hydrogen atom on the central carbon has been replaced by a methyl group. This structural modification results in a molecule that is not superimposable on its mirror image, hence its chirality. The enantiomers of propin exist as a pair of stereoisomers.
Despite its chiral nature, propin is not commonly encountered in natural sources. Its synthesis typically involves
