The valuable polymer polyurethane is made by a condensation reaction of alcohols (ROH)
Chapter 22, Problem 18.95(choose chapter or problem)
The valuable polymer polyurethane is made by a condensation reaction of alcohols (ROH) with compounds that contain an isocyanate group (RNCO).Two reactions that can generate a urethane monomer are shown here:(a) Which process,i or ii,is greener? Explain. (b) What are the hybridization and geometry of the carbon atoms in each C-containing compound in each reaction? (c) If you wanted to promote the formation of the isocyanate intermediate in each reaction, what could you do, using Le Chteliers principle?
