Molecule cis-1,2-difluoroethylene show symmetry elements
Make a model of each of the chair conformations of cis-1,2-dibromocyclo- hexane, and show that they are nonsuperimpoasble mirror images of each other. Is cis-1,2-dibromocyclohexane isomer optically active? The planar structure has a plane of symmetry, but the chair conformation doesn't! Yes _No Although each conformer is chiral, the rapid interconversion between the two at room temperature means they cannot be separated. The compound is not chiral. Identifying chirality in cyclohexane derivatives can seem daunting. Fortunately we can greatly simplify...
