C. Explain what changes in this system when one alters the solvent. Be specific about why the degree of stereochemical inversion varies, and why partial net retention is seen in trifluoroethanol. Diazo compound 4 undergoes a photolytic reaction shown below. A. Write a plausible mechanism for this reaction. Smog generation is an important environmental problem arising from reaction of photochemically generated species with organic compounds most commonly released from automobiles.
Concern remains over their participation in smog formation, however.
A. Suggest a set of mechanisms that reasonably explains the products observed. B. Smog is generated from reactions like aldol condensations of these organic products. C. Compare the danger of smog generation from oxygenates with the inherent process of smog generation from petroleum hydrocarbons. You may use hexane, benzene and toluene as model compounds for the hydrocarbons in gasoline.
