Question

The substances that sublime easily are:
(A)- Petrol, acetone, camphor, iodine and solid ${\text{C}}{{\text{O}}_{\text{2}}}$
(B)- Iodine, solid ${\text{C}}{{\text{O}}_{\text{2}}}$, ammonium chloride, kerosene and diesel
(C)- Iodine, camphor, ammonium chloride, anthracene and naphthalene
(D)- Iodine, acetone, camphor, petrol and naphthalene

Answer 1

Hint: First of all we will discuss the sublimation process before to ensure about the sublime substances, and sublimation is the process when a solid substance directly converts into a gaseous state without changing in the liquid state.

Complete answer:
Let we discuss in detail about an each substance in the following manner:
-In the option (A) Petrol, acetone, camphor, iodine and solid ${\text{C}}{{\text{O}}_{\text{2}}}$ are given but these all are not sublime substance because petrol is present in the liquid state not in the solid state.
-In the option (B) Iodine, solid ${\text{C}}{{\text{O}}_{\text{2}}}$, ammonium chloride, kerosene and diesel are given but these all are not sublime substance as kerosene & diesel are present in liquid state not in solid state.
-In the option (C) Iodine, camphor, ammonium chloride, anthracene and naphthalene are given and all these substance are sublime substance as they are present in solid state and possess sublimation process by directly converts into the gaseous state without changing into liquid state.
-In the option (D) Iodine, acetone, camphor, petrol and naphthalene are given but these all are not sublime substances as acetone & petrol are present in liquid state not in solid state.

Hence, option (C) is correct.

Note:
Here some may give wrong answers if you only observe the substances like camphor, iodine, naphthalene, anthracene & solid ice in the given options; by ignoring substances like acetone, petrol & diesel.
