Which of the following statements about crystalline solids is false?

Correct option is C

Crystalline solids are characterized by their well-ordered, repeating three-dimensional arrangement of atoms, ions, or molecules. They have distinct properties:
· Definite Geometrical Shape: Crystalline solids exhibit a regular and specific geometric shape due to their orderly arrangement.
· Sharp Melting Point: These solids melt at a specific temperature because of the uniformity in their bond strength.
· Isotropy vs. Anisotropy: Crystalline solids are anisotropic, not isotropic.
Information Booster:
1. Crystalline solids have long-range order in their atomic arrangement. Examples include quartz, diamonds, rock etc.
2. Anisotropy is the structural property of non-uniformity in different directions. An anisotropic object or pattern has properties that differ according to direction of measurement. For example, many materials exhibit very different physical or mechanical properties when measured along different axes, e.g. absorbance, refractive index, conductivity, and tensile strength.
3. The bonds in crystalline solids break at a single temperature, leading to a distinct melting point. Example: Ice melts at 0°C precisely.
