Current Question (ID: 17903)

Question:

$\text{The incorrect statement among the following regarding crystalline solid is -}$

Options:

1. $\text{Definite and characteristic heat of fusion.}$
2. $\text{Isotropic nature.}$
3. $\text{A regular periodically repeated pattern of arrangement of constituent particles in the entire crystal.}$
4. $\text{A true solid.}$

Solution:

$\text{HINT: Crystalline solids consist of atoms, ions, and molecules arranged in a strongly ordered microscopic arrangement.}$ $\text{Explanation: Crystalline solids are anisotropic in nature as this solid shows different physical properties such as electrical resistance, the refractive index in different directions.}$ $\text{Property}$ \quad \text{Types of solid} \quad \text{Physical properties}$ $\text{Isotropy} \quad \text{Amorphous solid} \quad \text{Same value}$ $\text{Anisotropy} \quad \text{Crystalline solid} \quad \text{Different values}$ $\text{So, option 2 is the correct answer.}$
