The compound which has the highest boiling point is n-Pentane. The temperature at which the vapor pressure of a liquid becomes equal to the atmospheric pressure is termed the boiling point of a liquid. Different liquids possess different boiling points due to the difference in n the intermolecular forces operating between the molecules of the liquid.

Compound with the Highest Boiling Point

The normal boiling point, which is the temperature at which the vapor pressure equals the average atmospheric pressure at sea level, is the point at which a liquid will boil regardless of the pressure being applied. 100°C (212°F) is the boiling point of water at sea level.

N-Pentane is a clear, colorless liquid with a petroleum-like odor. Its density is less than water; hence it floats on water. Also, it is insoluble in water.
