Looking up the structures of different zeolites (H-ZSM-5, Acidic Faujasite also known as Zeolite Y, and Basic Zeolite L) online, explain: 1. Which one would be good for converting isomerizing meta-xylene to para-xylene? Why? Explain in terms of pore size and acidity. 2. Which one would be good for serving as a support in converting linear heptane into toluene? What other component is needed to effect this catalysis? Explain in terms of structure. 3. Which one would be useful as an Fluid Catalytic Cracking catalyst and why? Explain in terms of pore size, acidity, and pore interconnectivity. 4. What is Lowenstein's rule? Draw a structural image with Si, Al, and O atoms to demonstrate it, including charges where necessary.
