Question

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 pentane (C5H12), hexane (C6H14), and hexanol (C6H13OH) are heated evenly at different altitudes, rank them according to the order in which you would expect them to begin boiling.
Rank from first to last. To rank items as equivalent, overlap them.
1. Hexane high altitude.
2. Pentane high altitude.
3. Hexane sea level.
4. Hexanol sea level

    Answer:

    Boils first >Pentane at high altitude> Hexane at high altitude>hexane at sea level> hexanol at sea level> boils last.

    Explanation:

    Step 1: To boil, a liquid must overcome the attractive forces between molecules and the outside pressure pushing down on the liquid’s surface.

    (Hexanol> Hexane> Pentane)

    Step 2: Identify which situation is most conducive to boiling

    To boil, a liquid must overcome the attractive forces between molecules and the outside pressure pushing down on the liquid’s surface.

    In which situation would you expect the liquid to boil first, assuming equal heating.

    (weak intermolecular attraction and low atmospheric pressure)
