4) Briefly explain why the following molecule cannot be produced using Williamson ether synthesis. 4 pts Note: a complete answer will illustrate the two theoretical William ether synthetic pathways that could be used to synthesis the product (1 pt each) and explain why each pathway would not yield the desired product (1 pt each). Bonus: Provide a different synthetic pathway that produces the ether shown above. (I could do it in a single step!). (bonus 2 pts).

The thermal decomosition of dimethyl ether (CH3)20(g) - CH4() + H2(g) + CO(9) is to be carried out in an isothermal, 4.00-liter laboratory reactor at 600.0 °C. The reactor is charged with pure dimethyl ether at a pressure of 350.0 torr. After about two hours, the reactor pressure is 725.0 torr. Taking elemental species (C(s), H2(9), 02(9)] at 25°C as references, prepare and fill an inlet-outlet enthalpy table. (See Example 9.5-2) Use tabulated data for methane, hydrogen, and carbon monoxide,...

1. For each of the following pairs of solute and solvent, predict whether the solute would be soluble or insoluble. After making your predictions, you can check your answers by looking up the compounds in The Merck Index or the CRC Handbook of Chemistry and Physics. Generally, The Merck Index is the easier reference book to use. If the substance has a solubility...
