1. Benzene is a planar molecule with bond angles of 120°. All six C-to-C bonds have identical lengths of 0.139 nm. Is benzene the same as 1,3,5 cyclohexatriene? Explain. 2. Write the chemical equations for the substitution reactions of benzene. 3. What are the properties of benzene that gives it its aromatic character? 4. Draw the hybrid structure of benzene. 5. Use the Huckel rule to account for the differences in properties of cyclooctatetraene from those of benzene. 1. Benzene is a planar molecule with bond angles of 120°.
