Question

NaCl has sharp melting point but glass does not have .justify​

Answer 1

Answer:

Crystals tend to have relatively sharp, well-defined melting points because all the component atoms, molecules, or ions are the same distance from the same number and type of neighbors; that is, the regularity of the crystalline lattice creates local environments that are the same. Thus the intermolecular forces holding the solid together are uniform, and the same amount of thermal energy is needed to break every interaction simultaneously.

Answer 2

Answer:

The Na + ions and Cl − ions alternate in three dimensions, repeating a pattern that goes on throughout the sample. The ions are held together by the attraction of opposite charges—a very strong force. Hence most ionic solids have relatively high melting points; for example, the melting point of NaCl is 801°C.

Glass is sometimes referred to as a supercooled liquid rather than a solid. ... The intermolecular force forces in amorphous solids are weaker than those in crystalline solids. Amorphous solids do not have a regular external structure and they do not have sharp melting points.
