WebThe central carbon atom of an allene is a member of two double bonds, and it has an interesting orbital arrangement that holds the two ends of the molecule at right angles to each other. (a) Draw an orbital diagram of allene, showing why the two ends are perpendicular. (b) Draw the two enantiomers of penta-2, 3-diene. A model may be helpful.

Understanding the 1,3-Dipolar Cycloadditions of Allenes

The central carbon atom of allenes forms two sigma bonds and two pi bonds. The central carbon atom is sp-hybridized, and the two terminal carbon atoms are sp -hybridized. The bond angle formed by the three carbon atoms is 180°, indicating linear geometry for the central carbon atom. The two terminal carbon atoms are planar, and these planes are twisted 90° from each other.
