Which term from the following is not related to adsorption?

Effluent

The correct answer is Option (2) → Effluent

Adsorption involves:

• Adsorbent → the surface on which adsorption occurs

• Adsorbate → the substance being adsorbed

• Desorption → removal of adsorbed substance

Effluent is related to waste liquid discharge and not adsorption.

Option 1: Adsorbent -This is the material whose surface adsorbs molecules. Directly related to adsorption.

Option 2: Effluent -Effluent refers to liquid waste discharged from industries. It is related to pollution control, not adsorption itself.

Option 3: Adsorbate -This is the substance that gets adsorbed on the surface. Directly related to adsorption. Option 4: Desorption This is the reverse process of adsorption. It is also related to adsorption phenomenon.

Option 4: Bromoethane and chloroethane - Similar polar molecules with comparable structure. Intermolecular forces are similar. Behave nearly ideal.
