Alcohols are very useful starting materials for the production of many different compounds. The following conversions, starting with 1-butanol, can be carried out in two or more steps. Show the steps (reactants/catalysts) you would follow to carry out the conversions, drawing the formula for the organic product in each step. For each step, a major product must be produced. (See Exercise 62.) (Hint: In the presence of H+, an alcohol is converted into an alkene and water. This is the exact reverse of the reaction of adding water to an alkene to form an alcohol.) a. 1-butanol butane b. 1-butanol 2-butanone
A chemical breathalyzer test works because ethanol in the breath is oxidized by the dichromate ion (orange) to form acetic acid and chromium(III) ion (green). The balanced reaction is 3C2H5OH(aq)+2Cr2O72(aq)+2H+(aq)3HC2H3O2(aq)+4Cr3+(aq)+11H2O(l)You analyze a breathalyzer test in which 4.2 mg K2Cr2O7 was reduced. Assuming the volume of the breath was 0.500 L at 30.C and 750. mm Hg, what was the mole percent alcohol of the breath?
