(2 points) Benzene consists of a ring of 6 carbon atoms, with one hydrogen atom bonded to each carbon. Draw the Lewis structure for benzene. Build a model (use black spheres to represent each C; white spheres to represent each H ). What is the electron group distribution at each carbon atom? What is the molecular shape at each carbon atom? Is benzene a flat (planar) molecule based on your model? Explain. Bond angle C-C-C? Bond angle HCC ? Based on your model, what would you predict about carbon-carbon bond lengths in benzene? ( C-C bonds have length of about 0.154 nm; C=C bonds have length about 0.133 nm.) Experimentally, benzene is found to have all carbon-carbon bond lengths the same at 0.139nm. Explain
