Given below are the temperatures at which two different liquid compounds with the same empirical formula have a vapor pressure of 400 torr.
 
 
 
Compound
T (°C)
 
 
 
dimethyl ether, CH3–O–CH3
–37.8
 
 
 
ethanol, CH3CH2OH
63.5
 
 
Which of the following statements is false?
 

​


◦ Increasing the temperature will increase the vapor pressure of both liquids.
◦ Intermolecular attractive forces are stronger in (liquid) ethanol than in (liquid) dimethyl ether.
◦ The normal boiling point of dimethyl ether will be higher than the normal boiling point of ethanol.
◦ The reason that the temperature at which the vapor pressure is 400 torr is higher for ethanol (than for dimethyl ether) is that there is strong hydrogen bonding in ethanol.
◦ None of these are false.
