1. Consider the following reaction - Dehydrogenation of Methyl Cyclohexane (MCH) to Toluene (TOL) using a Precious Metal (Pt) supported on Alumina. CH3 CH3 2 () + 3 H₂ Typically, hydrogenation of a cyclo-alkane, like MCH, occurs in 3 or more stages, where one bond is dehydrogenated per stage, eventually resulting in the dehydrogenation of 3 bonds. Strong adsorption of MCH is likely to occur, but the adsorption of hydrogen (either as a molecule on a single site OR as an atom on a single site) is unclear. Therefore, in this question, two types of reaction mechanisms are to be considered, as discussed below: (a) You are to first propose a reaction mechanism which includes adsorption, surface reaction, and desorption. For each of the following cases, please write down a full set of elementary reaction mechanisms.

1,4-Pentadiene (CH2=CH-CH2-CH=CH2) is a liquid at room temperature and has a density of 0.66 g/mL and molar mass of 68.12 g/mol. In a laboratory experiment, 3.80 mL of this compound was treated with 4.80 mL of conc. H2SO4 (100% w/w; molar mass 98.08 g/mol). Note that the density of conc. H2SO4 is 1.84 g/mL. The resulting sulfate ester was then treated with 1.20 mL of water (molar mass 18.02 g/mol) affording, after work- up, 2,4-pentanediol (molar mass 104.15 g/mol) as the crude product. The crude product was then purified by simple distillation, which yielded 2.00 g of pure product. What is the theoretical yield of 2,4-pentanediol expressed in grams? Show calculations. What is the percentage yield of pure 2,4-pentanediol?
