Interpretation: Whether the given statement and explanation given for the statement is correct or not needs to be identified.
Concept Introduction: The boiling point depends on the strength of the bonding between the molecules. If the molecules are tightly held with each other, a large amount of energy is required to break the bonds between them; thus, the boiling point will be high. Similarly, the boiling point will be low if a small amount of energy is required.
Explanation of Solution
According to the given statement, the boiling point of xenon is lower than neon.
The above statement is incorrect. The boiling of xenon is
The explanation for the above statement is given that there are strong dispersion forces between xenon atoms as compared to those between neon atoms.
The London dispersion forces are defined as the weakest intermolecular forces. It is a temporary force of attraction between molecules which is due to the formation of temporary dipoles as electrons from adjacent atoms occupy such positions. Here, xenon has strong dispersion forces as compared to neon atoms but due to this xenon has a higher boiling point.
Therefore, the given statement is not true. The true statement is neon has a lower boiling point than xenon. Although the explanation is correct for the true statement.
