Which of the following is not true with reference to evaporation of liquid?

The evaporation rate follows the order of Water > Alcohol > Ether.

The correct answer is Option (4) → The evaporation rate follows the order of Water > Alcohol > Ether.

Rate of evaporation depends on:

• Intermolecular forces

• Temperature

• Surface area

• Nature of liquid

Lower intermolecular forces → faster evaporation

Explanation

Statement 1

Liquids with weaker intermolecular forces require less energy for molecules to escape into vapor phase. Hence, they evaporate faster.

Statement 2

Higher temperature increases kinetic energy of molecules. More molecules acquire enough energy to overcome intermolecular forces. Hence, evaporation rate increases.

Statement 3

Larger surface area exposes more molecules to the atmosphere. Thus, more molecules can escape simultaneously. Hence, evaporation increases.

Statement 4

Actual evaporation order based on intermolecular forces is:

Ether > Alcohol > Water

Water has strongest hydrogen bonding → slowest evaporation Ether has weakest intermolecular forces → fastest evaporation Hence, given order is incorrect.
