Q:What is the point group of the following molecule? tetrafluoro cubane point grouplivrer de la nourriture non halal. Electric quadrupole moment. This is equivalent to saying that a n-fold rotation converts an object into its mirror image. tetrafluoro cubane point group. The former is chiral, but the latter is achiral because it has a S4 improper rotational axis (sometimes called an alternating axis). Since a plane or point of symmetry involves a reflection operation, the presence of such an element makes an object achiral. Finally, a rotational axis is designated Cn, where the degrees of rotation that restore the object is 360/n (C2= 180 rotation, C3= 120 rotation, C4= 90 rotation, C5= 72 rotation).
