Given Below Are the Temperatures at Which Two Different Liquid

question 110

Multiple Choice

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 (a-d) is false?

• A)Increasing the temperature will increase the vapor pressure of both liquids.
• B)Intermolecular attractive forces are stronger in (liquid)ethanol than in (liquid)dimethyl ether.
• C)The normal boiling point of dimethyl ether will be higher than the normal boiling point of ethanol.
• D)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.
• E)None of these is false.
