Atmospheric pressure decreases as altitude increases. In other words, there is more air pushing down on you at sea level, and there is less air pressure pushing down on you when you are on a mountain.
If hexane C6H14, octane C8H18, and octanol C8H17OH are heated evenly at different altitudes, rank them according to the order in which you would expect them to begin boiling.
A) Hexane at high altitude
B) Octane at high altitude
C) Octane at sea level
