Your answer: Option C

 \Large{ \underline{ \boxed{ \leadsto{ \rm{ \pink{Sodium \: chloride}}}}}}

Sodium chloride is not a volatile solid, hence don't sublime directly into vapours.

Explanation:

The process of conversion of a solid into gas or vice-versa without going into liquid state is known as Sublimation. And the opposite process of changing gas into solid is known as Desublimation or Deposition.

For Example: Ammonium chloride, camphor, Iodine, Napthalene, Anthracene,Solid carbon dioxide(Dry ice).

\large {\boxed{\rm{ \text{Solid}}}\overset{ \tt{Heating}}{\rightleftharpoons  \underset{ \tt{cooling}}}{\boxed{ \text{Gas}}}}

  • Sublime - A gaseous form, directly form from the solid on heating, is known as Sublime.
  • Sublimate - A solid state of matter formed directly from its gaseous state on cooling, is known as Sublimate.

❇ Here, Ammonium chloride, Camphor and Iodine are volatile solids which can directly change into gaseous state by Sublimation process. Sodium chloride is common salt. Imagine, If Sodium chloride would ever be a volatile solid, then we can't store and keep it in open. It can be made from seas by evaporating the sea water because along with water, the salt would have vaporise.

Hence, the answer is Sodium chloride.
