The ability of a substance to assume in two or more crystalline structures is called

Question

$\textbf{Reduction potential of ions are given below:}$
\[ \begin{array}{ccc} \text{ClO}_4^- & \text{IO}_4^- & \text{BrO}_4^- \\ E^\circ = 1.19 \, \text{V} & E^\circ = 1.65 \, \text{V} & E^\circ = 1.74 \, \text{V} \\ \end{array} \]
The correct order of their oxidising power is:

Answer 1

The question asks about the term that describes the ability of a substance to exist in two or more crystalline structures. Let's analyze the given options one by one to find the correct answer:

Isomerism:
This term is used in chemistry to describe compounds with the same chemical formula but different arrangements of atoms or different spatial orientations. It is not related to the crystalline structure of substances.
Polymorphism:
This refers to the ability of a substance to crystallize in more than one form or structure. This is a common phenomenon in solid materials, especially in metals, minerals, and polymers. Thus, this is the correct answer.
Isomorphism:
This term describes a situation where two compounds have similar crystalline structures. It is not related to a single substance having multiple crystalline forms.
Amorphism:
Amorphism refers to substances that lack a crystalline structure altogether. They are composed of atoms arranged randomly, such as glasses. Since the question is about multiple crystalline forms, this is not relevant.

Based on the explanations above, the correct answer is: polymorphism.
