Concept explainers
(a)
Interpretation:
The vapour pressure of methyl ethyl ether at
Concept Introduction:
Vapour pressure:
The pressure of the vapour when liquid and vapour are in dynamic equilibrium is called vapour pressure. It increases with increase in temperature. The molecule experiencing stronger intermolecular force of attraction, has lower vapour pressure.
(b)
Interpretation:
The liquid having strongest intermolecular attractions has to be determined.
Concept Introduction:
Refer part (a).
(c)
Interpretation:
The temperature at which benzene has a vapour pressure of
(d)
Interpretation:
The normal boiling point of the given liquids has to be determined.
Concept Introduction:
The temperature at which the vapour pressure of the liquid equals to the atmospheric pressure on the surface of the liquid is known as the boiling point.

- 5-106 The normal boiling point of hexane, C6H14, is 69°C, and that of pentane, C5H12, is 36°C. Predict which of these compounds has a higher vapor pressure at 20°C.arrow_forwardSilane SiH4, phosphine (PH3), and hydrogen sulfide (H2S) melt at 185 C, 133 C, and 85 C, respectively. What does this suggest about the polar character and intermolecular attractions of the three compounds?arrow_forwardChloroform, CHCl3, has a normal boiling point of 61C. Its vapor pressure at 43C is 0.526 atm. What is the concentration (in g/L) of CHCl3 when it saturates the air at 27C?arrow_forward
- Predict which liquid—glycerol, HOCH2CH(OH)CH2OH, or hexane, C6H14—has the greater surface tension. Explain your prediction.arrow_forwardp-Dichlorobenzene, C6H4Cl2, can be one of the ingredients in mothballs. Its vapor pressure at 20C is 0.40 mm Hg. (a) How many milligrams of C6H4Cl2 will sublime into an evacuated 750-mL flask at 20C? (b) If 5.0 mg of p-dichlorobenzene were put into an evacuated 750-mL flask, how many milligrams would remain in the solid phase? (c) What is the final pressure in an evacuated 500-mL flask at 20C that contains 2.00 mg of p-dichlorobenzene? Will there be any solid in the flask?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
- The 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_forwardAt a resort in Sante Fe, New Mexico, the barometric pressure is 625 mm Hg. Water boils in an open pot at 94.5C. A pressure cooker is set for 1.75 atm. (a) At what temperature will water boil in that pressure cooker? (For water, Hvap=40.7kJ/mol.) (b) What is the difference between the boiling point in the open pot and in the pressure cooker?arrow_forward8.87 Use the vapor pressure curves illustrated here to answer the questions that follow. (a) What is the vapor pressure of ethanol (C2H5OH) at 60°C? (b) Considering only carbon disulfide (CS2) and ethanol, which has the stranger intermolecular forces in the liquid state? (c) At what temperature does heptane (C7H16) have a vapor pressure of 500 mm Hg? (d) What are the approximate normal boiling pains of each of the three substances? (e) At a pressure of 400 mm Hg and a temperature of 70°C, is each substance a liquid, a gas, or a mixture of liquid and gas?arrow_forward
