Please outline a synthetic reaction scheme for the preparation of triphenylmethanol from:
1. Methyl benzoate
2. Diethyl carbonate
A large number of polycyclic benzenoid aromatic hydrocarbons are known. One of these, benz/a/pyrene, is a powerful carcinogen found in tobacco smoke. Draw the structure of this hydrocarbon. Can you suggest other sources where this material might be expected to be present?
