1. a) Draw the dominant Lewis structure for the allene molecule (1,2-propyl diene, CH2CCH2 ) and use VSEPR theory to determine the molecule's geometry. In specifying the geometry give all bond angles and specify which nuclei lie in the same plane. b) Propose a hybridization and bonding scheme for the atoms in allene. That is, specify how each of the atoms is hybridized, which atomic orbitals overlap to form bonding molecular orbitals, and the nature (i.e., 0", 7f, etc.) of these molecular orbitals.

c) Draw a plausible valence molecular orbital level diagram for allene (include only bonding MOs) based on the results from (b).
d) Based on the work from (c) deduce the valence electronic configuration of the ground state of allene.
e) Is the molecule planar or nonplanar? Explain your answer
