Topic V - Bonding II Pre-class Problem Allene is an unusual organic molecule in that it has two double bonds connected to the same central carbon: As depicted above, the central carbon is connected to two other carbons, which are each bonded to two hydrogens. . Draw the Lewis dot structure for allene. Identify the orbital hybridization and geometry at each carbon. Next sketch a valence bond orbital depiction of this molecule: first draw the sigma bonds, and then form the pi bonds from the remaining unhybridized p orbitals
