Which of the following factors contribute to the tetrahedral shape of the above molecule? Group of answer choices A. the shape of the two p orbitals in the carbon atom B. the shape of the one s orbital in the carbon atom C. the shape of the sp3 hybrid orbitals of the electrons shared between the carbon and hydrogen atoms D. hydrogen bonding configurations between the carbon and hydrogen atoms

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., sigma", pi, 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   Answer subparts c, d, and e

2) a) Consider the following molecule . Given what you have learned about hybridization theory, draw an image or images explaining the bonding situation in this molecule. I want you to draw out all of the orbitals, hybrid orbitals and how they overlap to form the bonds in the molecule. Indicate the % s or p character in the given atomic and hybrid orbitals. Which C-C bond or bonds are the longest? In a paragraph or so explain the image or images you just drew. b) Lastly, consider the molecule below. Indicate the Molecular formula, the molar mass, label the hybridization of each atom except for hydrogen, indicate any chiral centers with a *, which bond or bonds are the shortest, identify by name of each functional group with an arrow pointing to the group.
