Hi! Could you help me with the problem on the second picture please? The info about the experiment is on the first picture. Itâs about the dehydration of 2-methylcyclohexanol
In this experiment, you will study the dehydration of 2-methylcyclohexanol by treating the alcohol with sulfuric acid and heat, then analyzing the product by gas chromatography. This dehydration might produce 1-methylcyclohexene, 3-methylcyclohexene, or a mixture of both (Equation 4) OH H2SO4, Î (E1) (Equation 4) 2-methyl cyclohexanol 1-methyl cyclohexene 3-methyl cyclohexene According to Zaitsev's rule, when HX is removed from a species to form an alkene, hydrogen is lost preferentially from the carbon atom, of those adjacent to the carbon atom bonded to X, that has fewer hydrogens. Thus, the E1 reaction preferentially produces the most-substituted alkene product possible. This rule can help predict the product of many organic reactions, including the one above. However, an organic chemist cannot be sure whether a certain prediction is accurate until the reaction is studied experimentally, to find out whether it behaves in the expected manner. Your assignment in this experiment is to determine experimentally whether or not Zaitsev's rule is followed in the dehydration of 2 methylcyclohexanol. Once the alkene is synthesized, the Baeyer test for unsaturation can be used to detect the presence of double and triple bonds (alkenes and alkynes, respectively), as well as other functional groups that can be oxidized. The test uses aqueous potassium permanganate as an oxidizing agent, breaking the Ï bond in a syn addition to the alkene to form a vicinal cis-diol, in a mechanism similar to that of treatment of an alkene with osmium tetroxide (OsO4) followed by H202 and H2O. The purple MnO4 anion is reduced to a brown MnO2 solid, which precipitates out of solution
