Enantiomeric Cumulenes

In the following structures carbon atoms are dark gray and hydrogens are cyan. The molecules are initially shown as mirror images, and can be moved by clicking on the structure and dragging the mouse. Holding the shift key during this operation allows zooming. You should confirm the stereo-prefix assigned to each isomer by viewing from the end of the chiral axis. The last two buttons for each enantiomer identify the sp2 and sp hybridized carbon atoms by the designated colors.
