Question

Which of the following is in the correct order of boiling points for NaNO₃, CH₃OH, C₂H₆, and Ne?A) Ne < CH₃OH < C₂H₆ < NaNO₃
B) NaNO₃ < CH₃OH < C₂H₆ < Ne
C) Ne < C₂H₆ < NaNO₃ < CH₃OH
D) Ne < C₂H₆ < CH₃OH < NaNO₃
E) C₂H₆ < Ne < CH₃OH < NaNO₃

Answer 1

Answer:

D

Explanation:

Me has the least boiling point because it has the weakest degree of intermolecular forces. The weak van Der Waals forces exist in C2H6. In CH3OH, there are strong hydrogen bonds which accounts for the higher boiling point. NaNO3 is an ionic compound, hence it has the highest boiling point among all the substances mentioned.
