Dehydration (elimination of water) of 2-methylcyclohexanol can give either or both of two major products: 1-methylcyclohexene and/or 3-methylcyclohexene. The course of the reaction can be determined by analysis of the product using gas chromatography (GC), mass spectrometry, infrared spectroscopy, and refractometry.

The methylene was trapped in cyclohexene and benzene solution, and the four C7 hydrocarbon products (norcarane and 1-, 3-, and 4-methylcyclohexene) and their relative ratios were found to be identical to those produced in the photolysis of diazomethane in the former solvent. Similarly, cycloheptatriene and toluene were formed in a ratio of 1.0:
In the first step, the Mo₂C catalysts were shown to have sufficient acidity so as to catalyse esterification reactions at 180 °C and 10.3 MPa that stabilized the bio-oil. In the 2nd step of the upgrading process, the best Mo₂C catalyst 1Ni-10Mo₂C/ABC achieved 69% HDO with an overall carbon yield of 67% when operated at 350 °C and 15.0 MPa. ;

Q: On slide 130 for the first HNMR problem C9H11BrO, you said in class that 5 13C NMR would show that the product was monosubstituted while 4 would indicate a disubstituted pattern. In this case, we see 4 (157.5, 129.4, 120.4, and 114.4) high 13C spectra, but the compound is only monosubstituted. Why is this?
So now we have a carbocation bearing a methoxy group. The next step is 1) attack by water and ejection of a proton from the water to yield a neutral hemiacetal. Under acidic conditions the hemiacetal will hydrolyze to produce cyclohexanone and methanol. Methoxycyclohexane won't undergoe this reaction since there is no double bond to protonate.

Calculate the theoretical and percent yields. In the conclusions section, interpret the IR spectrum and compare it to the spectrum of the starting 2-methylcyclohexanol provided by your instructor. Draw a conclusion about the purity of your product based on this comparison. State and comment on the percent yield.
3) To produce 4-methylcyclohexene through the acid-catalyzed elimination of water from 4-methylcyclohexanol INTRODUCTION In this experiment, 4-methylcyclohexanol undergoes acid-catalyzed dehydration to give 4-methylcyclohexene. The product is distilled from the reaction flask along with the water generated. No, it would yield about 75% 1-methylcyclohexene and 25% 3-methylcyclohexene. A small amount of methylenecyclohexane will form as well, but it is very unstable and will likely convert into the ...

Mar 19, 2009 · This is also called the "theoretical yield." The percent yield is found by dividing the actual mass of product isolated, the "actual yield," which is given in the problem to be 0.484 grams, by the theoretical yield then multiplying by 100% to give the % yield. (0.484 / 0.79) x 100% = 61% Despite a short lifetime of 22.1(1) ns, the anion exhibited a photoluminescence quantum yield of 0.61(4) and fast quenching kinetics toward organohalogens allowing for its application in the ... Two parallel reactions took place, an isomerization to yield 1-methylcyclohexene and a decomposition to yield ethylene and isoprene. The ratio of products from each reaction path was essentially ... Jul 19, 2011 · Protonation of the Alcohol Group. An alcohols (-OH) is not a very good leaving group, because after it dissociates from a molecule it becomes a negatively charged hydroxide ion. Far better would be to first protonate the alcohol. This way it leaves the molecule as water- which has no charge and is very stable. Phosphoric acid gets this job done.

We would be seeing more 3-methylcyclohexene in the solution, than if we were using the cis variation. In Understanding the Experiment, 1-methylcyclohexene and 3-methylcyclohexene were mentioned as possible products of the dehydration of 2-methylcyclohexanol. Why wasnt 2-methylcyclohexene mentioned as a possible product? cyclohexanol. The phosphoric acid is a catalyst and as such increases the rate of reaction but does not affect the overall stoichiometry. It can be seen from the balanced reaction that 1 mole of alcohol produces 1 mole of alkene. The theoretical yield of alkene in moles is therefore equal to the number of moles of alcohol used. OH 85% H 3PO 4 ... Preparation of 4-Methylcyclohexene Introduction: In this experiment a very simple elimination reaction is induced to produce an alkene. The hydroxyl group of 4-Methylcyclohexnol is eliminated by protonation of a strong acid, H2SO4 and H3PO4. The 4methylcyclohexene produced is isolated and dried using distillation.
