Question

which noble gas has the highest boiling point? why?
match the items in the left column to the appropriate blanks in the sentences on the right.
the only intermolecular force present in noble gases is the, which increases with molar mass. hence, will have the highest boiling point.

Explanation:

Noble gases are non - polar, so the only intermolecular force is dispersion force. Dispersion force increases with increasing molar mass. Among the noble gases listed (He, Ne, Kr, Xe, Rn), Rn has the highest molar mass.

Answer:

The only intermolecular force present in noble gases is the dispersion force, which increases with increasing molar mass. Hence, Rn will have the highest boiling point.
