Question

Choose the odd one out. Give reasons for the choice.

a. Iodine, camphor, sugar, ammonium chloride.

Answer 1

Odd one out : sugar

Explanation :

1. Sublimation is the process by which a solid substance gets converted into vapour directly without forming the liquid.
2. Iodine, camphor and ammonium chloride all the three solids undergo sublimation because they all are volatile in nature.
3. On the other hand, sugar being a non volatile solid does not undergo sublimation.
