(choose chapter or problem)

Two molecules used in the polymer industry are azodicarbonamide and methyl cyanoacrylate. Their structures are O O O O N N N NH2 N H2C CH3 C C C C C H H a b e f h d g c Azodicarbonamide Methyl cyanoacrylate Azodicarbonamide is used in forming polystyrene. When added to the molten plastic, it decomposes to nitrogen, carbon monoxide, and ammonia gases, which are captured as bubbles in the molten polymer. Methyl cyanoacrylate is the main ingredient in super glue. As the glue sets, methyl cyanoacrylate polymerizes across the carboncarbon double bond. (See Chapter 21.) a. Complete the Lewis structures showing all lone pairs of electrons. b. Which hybrid orbitals are used by the carbon atoms in each molecule and the nitrogen atoms in azodicarbonamide? c. How many p bonds are present in each molecule? d. Give approximate values for the bond angles marked a through h in the above structures.
