    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?

    For your first question, the answer will be the same for both starting materials. You need to run the reaction with a high concentration of your grignard reagent, phenylmagnesium bromide. You have to drive the reaction to get rid of the side products, of methanol ...

    Solution Summary

    This solution outlines the reaction scheme of triphenylmethanol from two specific chemicals, as well as providing the structure of a specific hydrocarbon. Two diagrams are given to illustrate these reactions, and the answer is resolved by using these visual depictions and properties of certain chemicals/processes.
