However, that is not sufficient. You must have two cumulated alkenes (c=c bonds next to each other) with at least 2 substituents to have "axial" chirality. There is also helical chirality.

(A) Two bars stacked on top of each other can be viewed as a fundamental chiral building block and as an analogy to the well-known Born-Kuhn model. (B) The assembly supports two modes, which, if ideally tuned, lead to a single dispersive lineshape in the CD spectrum. The ORD ...
