(a)
Interpretation:
The structures of the ions making up [Bmim][BF4] and [Amim]Cl should be drawn.
Concept introduction:
Ionic liquids have lower melting points that is below 100 0C because those ions are poorly coordinated. Characteristics of these types of ionic compounds are at least one ion has a delocalized charge and one component is organic. This prevents it from forming a stable crystal lattice.
(b)
Interpretation:
Melting points of [Bmim][BF4] and [Amim]Cl should be found.
Concept introduction:

(c)
Interpretation:
The reason for melting points of [Bmim][BF4] and [Amim]Cl to be lower than that of NaCl should be explained.

- Butane is a gas at room temperature; however, if you look closely at a butane lighter you see it contains liquid butane. Explain how it is possible to have liquid butane present.arrow_forwardA solution of benzoic acid in benzene has a freezing point of 3.1 C and a boiling point of 82.6 C. (The freezing point of pure benzene is 5.50 C, and its boiling point is 80.1 C) The structure of benzoic acid is Benzoic acid, C6H5CO2H What can you conclude about the state of the benzoic acid molecules at the two different temperatures? Recall the discussion of hydrogen bonding in Section 11.3.arrow_forwardA 1.50-g sample of methanol (CH3OH) is placed in an evacuated 1.00-L container at 30 C. (a) Calculate the pressure in the container if all of the methanol is vaporized. (Assume the ideal gas law, PV = nRT.) (b) The vapor pressure of methanol at 30 C is 158 torr. What mass of methanol actually evaporates? Is liquid in equilibrium with vapor in the vessel?arrow_forward
- Define the normal boiling point of water. Why does a sample of boiling water remain at the same temperature until all the water has been boiled? Define the normal freezing point of water. Sketch a representation of a heating/cooling curve for water, marking clearly the normal freezing and boiling points.arrow_forwardConsider the following data for the vapor pressure of diethyl ether, a widely used anesthetic in the early days of surgery. Follow the instructions in Question 13 to estimate the heat of vaporization of diethyl ether.arrow_forwardIn the northern United States, summer cottages are usually closed up for the winter. When doing so, the owners winterize the plumbing by putting antifreeze in the toilet tanks, for example. Will adding 525 g of HOCH2CH2OH to 3.00 kg of water ensure that the water will not freeze at 25 C?arrow_forward
- What is the enthalpy change when a 1.00-kg block of dry ice, CO2(s), sublimes at 78 C? The enthalpy of sublimation of CO2(s) is 26.9 kJ/mol. Is this process exothermic or endothermic?arrow_forwardDiethyl ether (CH3CH2OCH2CH3) was one of the first chemicals used as an anesthetic. At 34.6C, diethyl ether has a vapor pressure of 760. torr, and at 17.9C, it has a vapor pressure of 400. torr. What is the H of vaporization for diethyl ether?arrow_forwardWhat mass (g) of ethanol, CH3CH2OH(), can be vaporized at its boiling point of 78.4 C by transfer of 500. kJ to the liquid? The vapH of ethanol is 38.6 kJ/mol at this temperature.arrow_forward
- The molecular mass of butanol, C4H9OH, is 74.14; that of ethylene glycol, CH2(OH)CH2OH, is 62.08, yet their boiling points are 117.2 C and 174 C, respectively. Explain the reason for the difference.arrow_forwardThe vapor pressure of ethanol, C2H5OH, at 50.0 C is 233 mmHg, and its normal boiling point at 1 atm is 78.3 C. Calculate the vapH of ethanol.arrow_forward
