8. Allenes are molecules where a carbon atom forms two different $$\mathrm{C}=\mathrm{C}$$ bonds with adjacent carbon atoms. The center carbon on an allene forms two $$?$$ bonds and two $$?$$ bonds. What is the hybridization of the center carbon? What is the hybridization of the terminal (i.e. at the end of a chain) carbon? Are the two $${\mathrm{CH}}_2$$ groups for allene present in the same plane (A) or are they perpendicular (B)? Circle the correct structure. Draw a valence bond orbital diagram to support your answer.
