Question

Which one of thefollowing decreases as the strength of the attractiveintermolecular forces increases? The heat ofvaporization. The normal boilingtemperature. The extent of deviationsfrom the ideal gas law. The sublimation temperatureof a solid. The vapor pressure of aliquid Hydrogen bondsaccount for which of the following observation? Hydrogen naturally exists asa diatomic molecule. Hydrogen is easilycombustible with oxygen. Water molecules are bent orV-shaped. Air is more dense thanhydrogen gas. For its molar mass, waterhas a high boiling point. Which one of thefollowing decreases as the strength of the attractiveintermolecular forces increases? The heat ofvaporization.

Explanation / Answer

As the strength of the attractive intermolecular forcesincreases, the extent of deviations from theideal gas law decreases. Each of the otherquantities is directly proportional to the strength ofintermolecular forces. Hydrogen bondsaccount for the fact that for its molarmass, water has a high boiling point. Hydrogen bond is one type of intermolecular force which ispresent only in water and few other liquids. Liquids withcomparable molar masses and no hydrogen bonding show lower boilingpoints. The weaker the intermolecular forces in a substance,the more it deviates from idealgas behavior Hydrogen bondsaccount for the fact that for its molarmass, water has a high boiling point.
