Question

Which of the following does not undergo sublimation?
a) Ammonium chloride b) sodium chloride c) dry ice d) naphthalene

Answer 1

Answer:

option c

Explanation:

So it can not change in vapour phase simply at atmospheric pressure hence it cannot sublime. Ammonium chloride, dry ice and iodine undergo sublimation which on heating without coming in the liquid state directly convert in a gaseous state.
