- Normal boiling point of ethanol (C2H5OH) is 78 °C, and of propanol (C3H7OH) is 97 °C. a. Explain the reason for the difference in boiling points of these two alcohols. b. When the underline methyl group in propanol, CH3CH2CH2OH, is replaced with a hydroxyl group (HOCH2CH2OH), boiling point of the molecule increases to 197 °C. Explain the reason for observed increase in the boiling point.arrow_forwardwhat is the name of this structurearrow_forwardConsider propane (C3H8) and decane (C10H22): Which is soluble in water? Which has lower boiling point? Which has higher boiling point? Which has lower melting point? Which has higher melting point? Vaseline, a complex mixture of hydrocarbons is used as a skin lubricant and ointment. Explain why Vaseline is insoluble in water but soluble in dichloromethane, CH2Cl2.arrow_forward
- In what way(s) is(are) the structure of H2O similar to that of CHCl3? In what way is the structure of water different from that of CHCl3?arrow_forwardYour roommate, a chemistry major, claims to have synthesized the compound CH5 in the lab. Why is that not possible?arrow_forwardA 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?arrow_forward
- Account for these facts: (a) Although ethanol (C2H5OH) (bp, 80 C) has a higher molar mass than water (bp, 100 C), the alcohol has a lower boiling point. (b) Mixing 50 mL of ethanol with 50 mL of water produces a solution with a volume slightly less than 100 mL.arrow_forwardComplete and balance the following combustion reactions. Assume that each hydrocarbon is converted completely to carbon dioxide and water. (a) Propane + O2 (b) Octane + O2 (c) Cyclohexane + O2 (d) 2-Methylpentane + O2arrow_forwardAssume that a car burns pure octane. C8H18 (d = 0.703 g/cm3) (a) Write the balanced equation for burning octane in air. forming CO2 and H2O. (b) If the car has a fuel efficiency of 32 miles per gallon of octane, what volume of CO2 at 25 C and 1.0 atm is generated when the car goes on a 10.0-mile trip? (The volume of 1 mol CO2(g) at 25 C and 1 atm is 24.5 L.)arrow_forward
- Would you expect butanone, CH;COCH;CH3 where the CO is a double bond, to have a higher or lower boiling point than acetone? Explain your reasoning. Propanol, CH3CH2CH2OH, has a molar mass of 60.1 g/mol and a boiling point of 97.4°C. Use intermolecular forces to explain why propanol has a higher boiling point than butane or acetone.arrow_forwardWhich of the compounds, ethanol, C2H6O, or methanol, CH3OH, should have the higher boiling point? Why? How would the boiling point change if the atmospheric pressure increased or decreased? What is the effect of small amount of impurity on the boiling point of an organic compound? List five physical properties of organic compounds that are often measured by organic chemists.arrow_forwardWrite the structural formula for propylene glycol, 1,2-propanediol. Why is it classified as an alcohol? Is it a polar molecule? Should it be miscible with water?arrow_forward
