Question

Which of the following statements is correct if the intermolecular forces in liquids $A,B$ and $C$ are in the order $A<B<C?$

• A. $B$ evaporates more readily than $A$.
• B. $B$ evaporates less readily than $C$.
• C. $A$ and $B$ evaporate at the same rate.
• D. $A$ evaporates more readily than $C$.

Answer 1

Answer: (D)

The liquid having low intermolecular forces evaporate faster in comparison to the liquids having high intermolecular forces. Order of intermolecular forces : $A<B<C$

Evaporation rate $:A>B>C$
