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

The correct option is D $A$ evaporates more readily than $C$

Answer is D

Strong intermolecular forces slow down the rate of evaporation.

If the intermolecular forces in the liquid are small, the molecules need little energy to separate from each other. The molecules escape into the atmosphere. The rate of evaporation is high.
