Question

The observation that ethanol (C2H5OH) has a higher vapor pressure than water (H2O) at the same temperature is due to more

A. Hydrogen bonding in the water
B. Kinetic energy in the ethanol
C. London forces in the ethanol
D. Hydrogen bonding in the ethanol
E. London forces in the water

What is the correct order for the surface tension of the following substances?

A. Hg, C8H18, H2O
B. Hg, H2O, C8H18
C. C8H18, H2O, Hg
D. C8H18, Hg, H20
E. H2O, Hg, C8H18

Answer 1

I believe that alcohols' higher vapor pressures than water is due to there being less H-bonding in alcohols, thus making the correct answer:
Is due to more [A. Hydrogen bonding in the water]
