Question

Which of the following will respond to sublimation?
1.Sodium chloride 2. Dry ice 3. Naphthalene 4. Ammonium chloride

• A. 1, 2 and 3
• B. 1, 3 and 4
• C. 3 and 4
• D. 2, 3 and 4

Answer 1

The correct option is D 2, 3 and 4

Sublimation is the transition of a substance directly from the solid to the gas phase without passing through the intermediate liquid phase.

Dry ice sublimes easily.

Naphthalene sublimes easily because it is made of non-polar molecules and has van der Waals intermolecular forces.

Ammonium chloride also sublimes easily but salt $NaCl$ do not.

So answer is $2,3,4$
